Just my opinion though.
Many brands have been bought out, like Windsor (really good), Carlton (meh) and many others. Hard nose bars (like Stihl Duramatic) can often be bought cheap now, but aren’t easy on the power head.
Ask yourself: Will I ever actually replace the tip on this bar? Am I buying this bar because it looks good on the saw? How much will this $200 bar get used?
Beware of used EBay bars. Shipping can be killer and you can’t inspect before you buy.
Personally, I like Tsumura Light and Tough. I hate saws pulling my saddle down and giving me plumbers crack. So light is right and Tsumura is cheaper. No complaints so far, 2 years in.
If you need a bar for a 50cc homeowner saw, just buy a cheap laminate. Even the Chinese ones will be fine.
