The brewing system depends on what you like in coffee. If you want the more floral notes, go with a pour over or Chemex. I'm not a huge Chemex fan, but occasionally make one.
My favorite pour over brewers are the Kalita wave and the Beehouse. I have a Hario V60 as well, but again it's not my favorite.
French press is a good choice for a full immersion brewer. Only issue is the sediment you get in the bottom of the cup. It makes a muddier cup, but more darker flavor. You get more of the oil from the beans.
Or, you can get the best of both worlds and get a Clever Coffee Dripper. You get full immersion and the pour over effect. Plus, it's cheap to buy.
I don't really have a favorite, just depends on my mood.
The grinder is extremely important in my opinion. I started with a Krups, then bought a hand grinder from Orphan Espresso. After I got tired of grinding by hand every morning I bought a Bunn grinder like coffee shops use. The hand grinder makes the most consistent grinds, but some mornings I'm lazy and don't feel like cranking it. The Bunn is nice.
For a home machine, I believe there are only 3 certified to brew at the right temperature. They are the Bunn Phase Brew, Bonavita, and Technivorm.
Now, if you aren't obsessed with coffee like I am, you can disregard my rambling.
