I've not tried all of the reds, but I've had a few ...

Red Rocket - good color, good growth

Arcturus - recent acquisition ... so far, so good. I like the bloom

Red Lantern - good color, but I had trouble growing it consistently

Bob Serbin - fairly good color, good growth, but leaves reached up too much

Secret Rendezvous - good growth, but didn't like the bloom color

July Renegade - good grower, but "dead meat" bloom color

-

Pow Wow - a fairly outstanding plant. Great intense bloom color

-

Hot Spot - a nice plant with nicely colored blooms. Grows well

-

Ogennyij Tsvetok - Russian Red bloomed pretty, but a bit challenging. Unfortunately, the blooms also fade after a bit ...

I may add some others as the day goes by ...
