Are you talking about actual RGB as in 12v, all LED change color at the same time, or ARGB which is 5v, and each LED can change color independently from each other? Because if it's the latter 5v strips don't work that well drawn out to a length of 15ft. The problem is the resistance in the wiring and the connectors causes what's known as power drop off. I'll give you an example from my own setup. These ceiling/wall strips in an aluminum corner channel is around 14ft of 5v ARGB. It's right at the cusp of major issues. When the white ripple wave of only 6 LED starts in the middle and moves outwards for a total of only 12 white LED, it causes a barely perceptible flicker in the blue. I can get away with it because the static blue running over the entirety is set to only 16% opacity which greatly reduces the power requirement so the full power blue ripple waves can be seen traveling over it. Now this is it set to white which uses the most power possible. As you can see the 90 degree corner connectors really adds a lot of resistance. That strip is also being run off of a Corsair ICUE's controller which are 4.5amp max devices because they are powered off a PSU sata power cable, and each sata power cable header is rated for a max of 4.5amps. The industry standard for motherboard RGB and ARGB headers is only 3 amps though. (Some MOBO now have 5A headers though)
Room size strips like the Govee brand for example always use 12v strips to get around the problem of power drop off. But they also don't have true ARGB. Their ARGB is only in sections of I forget how many LED that can change color independently of all the rest. Whole house setups like for many if not most of the neat Christmas displays are often using 24v strips. They'll also have extra power injection soldered into several to numerous places to help with the power issue.
To directly answer your question though, there is too many different ones to say which are bad, good, or best. There isn't any brand of LED strips that have gone on to be industry leaders. The best you can do is get ones from the larger manufacturers. Like BTF lighting are fairly large and their 100 LED per meter strips is what I used in the 2 middle towers, and 144 per meter in the smaller side towers I made, shown on my desk's hutch in the above pics. Their 30 LED per meter is also what's in the ceiling strips.
Okay, sorry for the day late response. But here we are.
So the strips I'm currently looking at are these. Now I havent finished my research on them, but I know the company sells little controllers for these. Basically like a tiny box that you can program the strips with.

Otherwise, any regular LED strip usually has about 16 colors with a remote. Some are sound activated, some arent etc. You just have to shop for what your desired effects are. The best place for recommendations if you dont wanna do research are the ones pinned at the top of this subreddit.
Now Phillips hue, which I'll provide a link for as well, are one of my favorites. They offer over 16 million colors to choose from and should be operable via your phone. The downside is that the strips are shorter in length and require extensions and a hub. Basically the core stip can have a certain amount of extensions(cant remember if it was two or three), but that means you'd purchase, depending on the size of your room, 2 to 3 regular strips, plus however many extensions, and a hub. Without the hub you cant control the strips. Sucks, but tbh I think the amount you can do with these makes it worth it to put up with purchasing a hub.

*Note: These are all just Amazon links to the individual products. Sometimes you can find Phillip's starter kits that include the hub, most common being with their LED light bulbs set. So depending on how much your budget is and how much you like the product, you can try to get more for a cheaper price via these kits and places like ebay/offerup/mercari.
Now If were talking laser light. I'll send a link to the one I'm looking at myself, but these you really should put your own time into researching. There are a lot of different models and brands that do a array of different projections.
This is the one I'm looking at on amazon right now, but I'm still not set on it.

Lastly, just as a extra addition. I bought this lovely "laser" and wave projector light. You can definitely find better ones on amazon, but I heard this one was silent running so I immediately grabbed it. I love it, but it has two issues for me. The laser "pulse" setting, where its supposed to slowly fade in and out like stars is choppy. Meaning it fades a little, stops, little more, stops, off, then on a little, etc. Second, the bluetooth sucks. It's not loud AT ALL. But the sound activated mode is super nice imo. Just turn it the lowest u can that it still functions, and play the real music louder somewhere else. Easy.
Here is the link to mine. However, amazon sells SOO many copys of this for cheaper. Just take some time to look through the features, customer reviews, and most importantly, customer videos/photos.
