I would not recommend either. Pick one out of this list instead: https://www.gotaukulele.com/p/ukulele-reviews.html?m=1. Tenor is a popular size. Concert would be fine too.
Don't buy the uke from Amazon. Try Mim's Ukes, which will set up the instrument for free: https://mimsukes.com.
Don't buy a starter kit. Buy a Snark tuner: https://www.amazon.com/dp/B01H74YXNQ/ref=cm_sw_r_apan_i_6A770C3QDY1GVMAYNS6H. Buy a few sets of fluorocarbon strings--Fremont are good, my favorite are Living Water. A linen strap and a bag are nice to have too, but not essential.
That's all you need right now.
