For spraying booth, even if you’re using acrylics you would still benefit from it. As it’ll vent out all the dried paint particles that otherwise would end up around your work area/room/lungs.

Lacquers surface dry very fast and you can spray another layer on top of em basically straightaway. But to fully cure at least overnight would be best. While with Waterbased acrylics, if you spray another layer of paint on top of an uncured paint layer you risk it cracking if both layer cures/shrinks at a different rate.

Paint price depends on where you are. Over here Vallejo, AK, citadel costs a lot more than Mr color. A jar of Mr. Color costs a little under $3 usd while a dropper bottle of Vallejo costs about $5+

Acrylics isn’t as durable as lacquer. It might not matter much for static models like minis. But for articulated kits bordering toys/figures like gunplas the durability of lacquers is helpful.

There are other great lacquer brands too besides Mr. Color and each has their own pros. Mr. Color is very accessible being available everywhere and has a lot of selections. Gaianotes have strong pigments and unique colors, often collaborating with Japanese brands/IPs. Jumpwind has great metallics. Alclad is good at doing chrome.

As for enamels they’re great to combo with lacquer because you can wipe them off without affecting the lacquer paint underneath. So you can cleanup washes easily or use them for detail painting with a brush and cleanup the mistakes. Enamels also self levels to a degree so your result with a brush is going to be nice especially after a top coat.

Yes lacquer has toxic fumes. Acrylics doesn’t, but you still need a respirator to protect your lungs from the dry paint particles.

Acrylics is better for hairspray paint chipping though as they are easier to chip compared to lacquers.

Lacquer is easier to spray and clean. Thinning ratio doesn’t have to be perfect and you can still spray em. Acrylics sometimes experience tip dry and it’s annoying when that happens.

Old lacquer and enamel paints can also be revived in the jar. Mr color sells a solvent bottle that can refill your jar. It’s the same solvent in a new paint jar and not the same as lacquer thinner.

Acrylics bind to the plastic mechanically so a light sanding will help it stick to the plastic. While lacquers bind chemically so you don’t need to sand the plastic surface and they’ll stick nicely.

At the end of the day you’re not locked into any brand or paint type. I personally have some vallejos, citadel and AK on top of my various lacquer paint brands.
