“RC-1 was more quiet than the RC-3, but indistinguishable from RC-5. I ended up using the RC-1 more because the RC-5 is a pain to set up for simple looping without tempo sync. I'd say go for it.”— jonslow1212 on Reddit
“I use an rc1 as my main looper for practicing and for playing on live streams. The rc1's visual loop display is extremely helpful and that's something the rc5 does not have.”— AxelAlexK on Reddit
“If you are looking to use it live, the stop/start functions seem a little clunky to me. I don’t have experience with others, but I’m hesitant to use it on stage for that reason.”— ZappVanagon on Reddit
“The Keeley compressor has been on my board for a long time and it works well for me. I switch guitars between a tele and a es-135, so the simple single coil/humbucker toggle switch is a very useful feature.”— Sensitive-Muscle2606 on Reddit
“I'll say the only reason I left the Keeley for the Wampler was because the Wampler comes in mini... Both are great. Love the pickup switch on the Keeley too”— chancesteward on Reddit
“My compressor Plus buzzes like crazy with my single coil guitar and it drives me nuts. I find if you turn down the sustain knob it helps, but having extra sustain is kinda the point.”— MedicineforMadness on Reddit

Owners point the Keeley Compressor Plus at players switching between single-coil and humbucker guitars on the same board, and anyone who wants an always-on compressor that can be dialed back with a blend control.
The most-cited downside of the Boss RC-1 Loop Station is stopping takes a double tap and clearing takes a press and hold, which owners fumble in the middle of a song. For the Keeley Compressor Plus, it's audible hiss and broadband noise, by far the most common owner complaint.
