I'm finding my Anet A8 Plus a reasonable printer. I received it as Christmas gift from my family, which was unexpected, so this review is made without considering price too much.
Biggest complaints are the bed size is too big for what I need, which has made finding PEI sheets for it a pain. The glass print surface is a real pain to print PLA on. I don't like PLA that much for printing though.
Print quality is pretty good once all belts well tightened and bearings lubricated. Original Y-axis bearing failed after 3 months printer usage causing failed 8 hour print

But after lubricating the bearings all seems well.
Bed heater could be more powerful for its size: takes quite some time to get to 85C (at least 15 minutes) and is operating near 90% duty at this point, so max temp is probably 95C. This means some will struggle with high temperature filaments that need 100C+ bed temperatures. I am considering adjusting the PSU to 28V output, to improve bed heating time. The current PSU has 50% overhead in its power rating, though it is a Chinese special so its 360W rating (and non-PFC nature) are somewhat dubious.
Controller already fried when I accidentally shorted 24V to the thermistor for the extruder. AVR did not survive (perhaps unsurprisingly, although only the ADC part was defective) but that was not too hard to replace. The microSD slot has broken (not retaining card any more) after 100+ ejection/insertion cycles, so that needs to be repaired.
My overall experience is that I much prefer PETG filament, I find PLA to be too difficult bed adhesion wise without assistance (e.g. gluing or super hot bed temperatures). PETG almost adheres too well, but I've had very few prints fail with it once everything is well adjusted. The worst thing about PETG is the stringiness, which I've managed to minimise but not completely eliminate. Some brief post-processing with a hot air gun and a set of files deals with these well enough.
