I had the Thule Apex XT 4 as well before, and mostly used it on our Honda Pilot (sold it before getting our Model Y).
It's a decent rack when you only want to carry 1-3 bikes at max, if they're not too heavy. I've loaded 4 bikes on there and you really need to strap everything down so they don't move or wobble while driving, or start swaying back & forth when you're accelerating & braking. Also, I could see the rack flexing quite a bit on the freeway if I went over a bump. IMO, it's a good rack if you want something smaller and compact, and if you aren't carrying a lot of heavier bikes on it. Also, if your top tube isn't high enough to mount onto the rack, then you will need to by an extension piece that goes from the stem to the seat post, and we had to do that with a few of our bikes. Not the most secure method but the only way to fit the bike on the Apex XT.
I've since switched to a platform rack and ease-of-use with it makes it so much nicer & better to use than the Apex XT. The main thing is I can quickly load up each bike and they will not touch either, nor will they move or sway while I'm driving. And the best part, takes me literally 20 seconds per bike with the platform rack, where it took me a few minutes to mount & hang each bike and secure them with some towels in between the bikes so they don't rub (which happened on the very first trip and sure enough my frame had a big nick in it ever since). The bad part about a platform rack is the weight and they stick out further from the car, so the weight distribution with 4 bikes loaded up may seem a bit daunting, so you'll want to make sure you invest in a good quality brand & rack. I'm using a 1UP Super Duty double rack and have 2 extension add-ons for it. It's really heavy with all 4 racks connected (approx 110 lbs), but man is it rock solid on the car. I haven't put the 1UP rack onto my Model Y yet, but I probably will this holiday weekend when we go out riding.
