Well, Bandai decided they were going to make the best SW kits out there, and they had the financial muscle and engineering talent to pull it off. I give their corporate suits credit to be bold enough risk a high cost (Disney licensing) line of products they never did.
To be honest, the sci-fi stuff coming from the other companies look like molded soap bars by comparison.
I beg to differ. Fine Molds made Star Wars kits in the early 2000s. While their line wasn't long, because only five Star Wars movies were out, they made a handful of high quality 1/72 scale kits along with a couple of 1/48 scale kits.
They made Luke's X-Wing, Y-Wing, TIE fighter, TIE Interceptor, the very nice Jedi fighter Obi-Wan uses against Jengo Fett, two different Slave 1s: Jengo's and Boba's which comes with a white metal Han Solo frozen in Carbonite. And one of their finest ones, the 1/72 scale Millenium Falcon. All in 1/72 scale.
In 1/48 scale, they did the X-Wing and snowspeeder. I've got all of them but the 1/48 X-Wing and Falcon.
Revell of Germany also produced some very nice box scale kits. A lot of the smaller ones were sold in foil bags in the US. They were snap together, but highly detailed with most kits based on the TV series The Clone Wars. The Revell Republic Star Destroyer is a topnotch kit. It dwarfs the old MPC Star Destroyer.
Most of the original MPC (later AMT/Ertl) kits are forgettable. The Gungan sub and twin pack of droid fighters were really decent as was the Naboo fighter.
Don't get me wrong, I've got over a dozen Bandai Star Wars kits. They are great model kits, but they are not the only ones that put out high quality Star Wars models. Revell's Kylo Ren command shuttle is a very nice kit, but Revell's scales are all over the place.
