I don't think the brand of the holder, or the insert really makes much difference for hobby use, on hobby machines where the speeds are quite low and there isn't a need to maximize efficiency. The cheap, imported tool holders direct from China on eBay, from Amazon, or places like AliExpress work just fine as do the inserts. What I do is buy a pack of inserts with a holder and if I like their inserts, buy a bunch of them the next time I order something.
For smaller machines stick to an insert with positive rake. CCMT, TCMT and DCMT insert styles would probably cover 99% of most facing, turning and boring. In many cases you can find both turning/facing and boring holders that use the same inserts, so that helps cut down on the total number of insert styles you need to keep on hand.
A kit like this will set you up for turning, facing and boring for very little money.
