If I’m not mistaken, a size 5 fits larger than a 5T. My mom asked a sales associate about the difference between the “T” sizes and just the numbered sizes last year, and I believe she was told that the T sizes fit smaller.

In our experience the non-T boy sizes fit a bit looser and longer than the T sizes. It feels as if they're cut to be similar to the "big boys" rather than the cute little boy clothes. So shorts are longer and t-shirts are looser. I don't feel like I've noticed a difference in pants.

I’d go with the 5! My almost 6 year old is about that size and 6 swallows him up (in every direction, he’s fairly tall and slim) but 5T is too short.

My DS is also in that transition place with sizing. He is on the shorter size so I did some 5T pants since they are a little shorter but also picked up some 5's to grow into. For tops we moved right into 5/small in boys so that he could wear them longer.
