CT toys is currently some of the best value for their price and quality.
Transformers also has a lot of great quality KOs, both of official product(which has been lacking as of the last few years, but still plenty of older figures that hold up) and third party toys.
Most other things can be a crapshoot. NECA KOs can be close , but due to attempting to mimic the paint apps with little QC means you have a lot of issues with stuck joints. Generally revo, figma and SHF KOs will be pretty terrible and not hold up to much play, but may look ok initially for the price.
