Bang for buck: Ender 3
Small but mighty: Prusa mini
Best performance/dollar: Prusa i3 MK3S
With the exception of the mini I have used and owned these printers. The Ender will give you a lot to learn and improve on. The prusas are good right out of the box. If you like tinkering and want to learn the fundamentals of 3D printing the ender is a great place to start. If you want to get up and running fast and not think about how level your bed is or if your print will be OK unattended, get the prusa.
