TB6600 drives are OK if you get genuine ones, and don't push them too hard by running near the maximum voltage.
The 'fake' ones, don't even use a TB6600 chip. You can usually tell the fake ones, as they have a 32x microstep setting, which the TB6600 chip isn't capable off.
I'm using A4988 in the end after researching I just have to make my own PCB lol

Not really that complicated I bought a PCB board from Ali, some sockets, resistors, pin headers ,etc

So I'm going to socket the A4988 before it connects to the Pi which means i can just swap another one if it fails they're cheap and I have multiple

BUT I went with them because for the kind of motor I have these give best microstep performance for resolution as long as you have more than enough torque

They also work at 3.3v for step/dir without having to wire in a transistor as the PI is 3.3v at the GPIO pins
