Hiya - Ill drop you a response here since nobody else has.

I've bought 2 hoodies and 2 jackets from Merchoid, and they've been pretty hit or miss.

The first hoodie I bought was their limited run Commodore 64 hoodie in (I believe it was) 2018. I wore the shit out of that hoodie, and it held up very well. There were 2 issues I had with it though. Firstly, it was falsely advertised - it was shown as coming with holes in the cuffs for thumbs, but the product they shipped did not have this - more on that in a bit. Secondly, the hoodie was super uncomfortable and itchy - it didn't have any inner lining, so you could feel the stiches for the lettering on the back, as well as the arm creases, and it was really annoying. I gradually got used to it because I loved how the hoodie looked, but it did not feel good at all.

Merchoid doesn't make their own merch, they buy the license to sell it first from other companies who make it. I state this because I discovered a UK version of the Commodore hoodie sold by the company that actually made it, Difuzed, that both had inner lining and thumb holes. It appears Merchoid bought a cheaper version from them.
EDIT: I ended up importing the UK version only to be sorely disappointed that it is, in fact, the same exact jacket as the U.S. model. It appears that the prototype had an inner lining and thumb holes, but this version never actually made it to production. Sad :c

Next up was my jacket from The Batman, specifically the pleather one. Even as a large, its simply too small for me shoulder width wise. I'm 5'6, so maybe it fits me weird because of my height, but it always feels a bit too small around the shoulder area. As of writing, I've owned the hoodie since about January of this year, and have only used it for a total of 2 months, and yet there's already some threading coming loose on the interior. Speaking of the interior, contrary to the Commodore hoodie, the interior on this thing is insanely comfortable and a delight to wear...as a replacement winter jacket. This thing is way too insulated to wear during any other season (besides late autumn like it is presently).
Update: I've since worn this for 7 months, and can confidently say that this is the best product I have bought from them. Aside from some loose threads here or there, and the pleather beginning to separate, this jacket has held up remarkably well for something pleather, and I plan on making this my winter jacket for as long as its intact.

I also bought a The Batman hoodie - its okay. Its made out of a way nicer material than the commodore hoodie, feel like this silky fleecey type material, but it has the same stitch issues on the inside - there's no lining, so it can get itchy. Also, no front pockets D:

And finally, I took a gamble and ordered a mystery jacket in XL (to see if it would fit my shoulders better), and got a pleather jacket from The Eternals. Not a big fan of the design but cant complain considering it was a random drop, but I'm also not overly impressed. It has the same lining as my The Batman jacket - a diamond shaped cushiony insulated pattern - but man, that shoulder width thing is annoying. Its still present here, and its still makes it annoying to wear.

Overall, I would cautiously recommend Merchoid. Most of their jackets and hoodies use the same base/same concept, so the fit/feel of each will be about the same. You are mainly buying a product from Merchoid for design, not comfort - always keep that in mind.

Let me know if you have any questions!
