The revell kits are actually surprisingly nice for the most part in my opinion (apart from the Falcon, but then again, it looks like they used the same exact masters/source as the Code 3 one).
The only real negative criticisms I have is simplified details to facilitate snap together assembly at a low cost and box scale. Even at box scale, you'll often find many subjects happen to wind up around the same scale, although that is usually not a standard and winds up being things like 1/53, 1/65 etc..
I fell they typically wind up more accurate in shapes than the old MPC/ERTL stuff, but not as detailed as Fine Molds/Bandai
But then again, even a company like Fine Molds was criticised for not having accurate detail. Look at all the work it takes to make their Falcon match the studio model
They are typically affordable (at least when in production and not sold by scalpers on eBay) and a great way to test your detailing skills. I feel much better experimenting with detailing a revell kit than an expensive fine molds kit and in a way find it more rewarding
I have a number of kits.
I think the general consenus for the best kits are the Easy Kit Tie Fighter and Venator Republic Star Destroyer.
Other than those two I liked pretty much every one I've seen except the Falcon. But then again, I've seen lots of great conversions and kit bashes of YT variants come from it
I liked the ARC-170 kit apart from the non existent cockpit details. but that was a fun and easy fix
The Y-wing was decent apart from the molded on pipes. But in some ways i think they got the shapes better than the fine molds one. The neck of the Fine Molds on feels too "fat" and the engine rods seem to long
The pocket snowspeeder was also a nice kit. A little mod to make the air flap raised
I think even with nothing more than a few added armor plates and replacing gun barrels and even the AT-AT with no other work done looks good once painted
The Pocket Kit Eta Starfighters are pretty good. I have them in the queue.
The Slave-1 kit was also a nice surprise when comparing it to the Fine Molds kit as far as details
Here is a build thread I have going
