it will depend on what your thinking about doing. are you going to dedicate it to the table? answer these questions first.

generally people use a router table for work that would be dangerous if done by hand or requires very large cutter or cannot be done off the edge via a roller bearing.

making millwork for doors or windows, raised panel doors, stick and cope cabinet door construction, pattern routing...

I would start with the router table I wanted first? then work back to the motor/size brand that fits your budget.

your going to get all kinds of answers from /r/woodworking on tool brands. it's like a religious type of thing with most people.

Hitachi, Dewalt, Porter Cable all make very nice routers. my jess em table has a larger porter cable and it has run thousands and thousands of linear feet of material.
this one, it used to be the largest router they made. I don't know if that is true anymore but for a router table, go big.

although I have only really been buying festool stuff for the last 3 or so years and would never go back to the other brands, but I know that is not an option for everybody and some like to just hate the festool stuff because it's very expensive. For me the $ is not an obstacle and they are the best production quality machines out there.

once again I'm a heavy user, as close to prosumer wood worker as you can get and have been doing it for a long long time.

edit:
also put one of these on your table router if you can

makes changing bits super easy, no more busted knuckles. I think white side also has something like this?
