Fully custom for an individual is pricey with setup costs, but is good on a team basis.
Semi custom is better value, you pick from a selection of designs and get your name etc added.
Your next choice is what physical design of jersey you want - just a jersey, or extra padding in areas, integrated ‘sleeve gloves’
I have a couple of Jerseys clinic jerseys, just their off the shelf options and a team branded set.
With a tournament team Amped, we had a full custom design and can buy any product in their range using the design - jersey, t shirt, hoody, shorts, head wrap, barrel condom etc
