Lots of great options these days. The Strymon Big Sky seems to be the reigning king currently. It's far too much pedal for me though. I love the Neunaber Wet (the hall and plate algos are fantastic as well). Last year I switched back to the Boss RV6. I realized that there are some amazing players (James Duke, Daniel Carson, etc) still playing their RV5s and they sound amazing and have no trouble getting gigs. I went with the RV6 because I like to use the expression control to give me on-the-fly control of my mix (essentially allowing me to change my reverb without needing a pedal with presets). The RV6 sounds great and has a good buffer in it which i find is often helpful at the end of my chain. It may not be the absolute best but it sounds great and packs good value.
