the two best jangos for that scale:
fett evolutions multipack & vintage collection
hunt for those on ebay or just put a search reminder. Glue the holster to the thighs so it doesn't float in the air. If you think the evolutions jango is too purple, just repaint the bodysuit and it will also give it a nice matte cloth effect (just avoid glossy colors). You can also repaint the metal plates for even more shine.

Hasbro always gets shit wrong so its a big relief to be able to correct their mistakes with acrylics (e.g vallejo game/model colors)
also keep any old jango accessories you have (early 2000s jangos may have pistols in higher quality plastic etc) and you can use them on a newer jango. The TVC Jango I have, had terrible pistols, really soft and they were actually missing part of the sculpt at the bottom. (I guess they were trying to save costs because of the other accessories.) Just go on rebelscum or any site and compare. I used pistols from another Jango I had that didn't bend very easily.
Unfortunately Hasbro and especially 3.75" collecting is not black and white at all, newer is not always better (although it usually is). Sometimes old figures have more accessories and so on but worse paint and sometimes its the opposite. I've found out even older figures have their uses. 3.75" star wars is just weird like that, but it's fun because you can get creative with it.
another weird example of hasbro quality:
2006 saga collection cody has more accurate decals than TVC or black series. He has some alien writing on his shoulder pad that the others don't have.
