It depends which ones as Makita don't actually manufacture any drill bits themselves. As Tucker said, single drill bits rebranded by companies like Dewalt or Makita will usually be decent, but these cheap, big sets are usually aimed at the DIY market and as such will have been sourced from China and won't be as good quality as a drill bit manufactured in Germany for example.
These diy sets will still work fine though. They will get the job done, but just won't stand up to the daily use a tradesman would put them through and they are priced to reflect that. Theres no point spending £100+ on a large set of quality drill bits when you'll only use 2 of of them to put a shelf up

. The Von Haus set you posted should be fine for what you need.
