I used to be obsessed with models 30-35 years ago. I have never built anything from Tamiya but their paints are great. Hasegawa is the gold standard and but I only made a couple of those because they were expensive as hell. Testors was probably the brand I bought most and they fit cleaner than Monogram and Revell (I think Revell has long since bought out Monogram though). If you ever do WWII planes, Korean War, or early Cold War when a lot of them were unpainted the Testors metallizer paints look spectacular, though they require you to use an airbrush. And to be honest I don't even know if they sell them anymore lol. But my P-51 Mustang, MiG-15, B-29 Superfortress, F-86 Sabre, F-100 Super Sabre, F-104 Starfighter, F-102 Delta Dagger, B-52A Stratofortress, and B-58 Hustler I did with those all looked like they were legit metal after I was done with them. I'd also say the tube plastic cement worked way better the liquid one you brushed on. Definitely agree on 1:48 scale, they look so much more impressive when you're done than a 1:72 scale model.
