That site just sells cheap Chinese junk. I'd prefer major electronic component distributors like Mouser or Digikey.

The ones on mouser/digikey are probably made in the same factory, they just have more middlemen.

Stuff you see on Alibaba doesn't even say what company made it. At least on the sites I listed it says the name of the manufacturer. Also I think that Mouser and Digikey are direct distributors for most electronics manufacturers. They buy products from the manufacturer, then sell to the consumer. Same as Alibaba. Except with Alibaba you don't know if it's a legit company, or some no-name shady business selling it through Alibaba on behalf of the real manufacturer, concealing the identity of the manufacturer.

Why pay more for it then needed when it is just a simple pcb without components on them. Order a bunch for each size and you are basically set for life. Even if the quality is a bit sub par, which to my experience it is not, as long as only used in prototyping it does not matter. But hey, it is your money :)

Typically the self branded stuff from distributors is worse in quality compared to what you buy from Aliexpress or Ebay.
Where it comes to prototyping smd parts: use veroboard and solder components on the solder side and/or mount chips dead bug style. If you can wait a bit just make a board that has some flexibility for experimenting. Much more reliable than using any breadboard solution
