Check your local maker space / hacklab first to get started. SLA printing isn’t for everyone and cheaper gear isn’t so nice to operate. You should also consider washing & curing station since it’s really a must if you want to print at least somewhat comfortably.
Mostly the difference is how locked down the printers are. For example I really don’t like Elegoo’s proprietary slicer format as it requires me to use their shitty closed source slicer. Second is the availability and pricing of spare parts.
Washing and curing stations are quite simple and as far as I know there’s no big differences.
