Concert Archives says I've been to 103 venues. It would take a lot of time to really dive deep. I've seen the most shows at the Ogden Theatre in Denver (25 shows), 2nd is the Fillmore Denver (20 shows), followed by Fiddler's Green Amphitheatre (18 shows), Pepsi Center (17), and Red Rocks (16). The Ogden is great. Not too big, not too small, multi-tiered so lots of great viewing. The front pit is real small, which is challenging during busier shows because it gets just too packed. But most of the time, plenty of room to move around. The Fillmore, alternatively, is one giant GA floor, gets pretty crowded and very hot. Will always prefer the Ogden over the Fillmore.Pepsi Center is what it is...an arena. I've seen some great shows here. In terms of an arena experience, pretty standard. The two amphitheatres really steal my heart though... Red Rocks is obviously fantastic - great sights no matter where you're sitting (although I've always been in the front half of the rows). I've never seen a show here in inclement weather, so I've always gotten lucky. However, it is a little bit of a drive, and once you're there, it's a hike. When I used to be really overweight, I really struggled getting up to the venue. Now that I've gotten in shape (in part due to morning exercises AT Red Rocks), it's kinda fun to scurry past others who are struggling to get up the ramps/stairs. Also, the ticketing at Red Rocks can get a little crazy - some shows are all GA, some are all reserved, but a lot of shows are a mix. They do this thing often where the first 20 rows are GA, as well as the last 10. So if you don't get into the front 20, you get screwed and have to go all the way to the top. Fiddler's Green Amphitheatre is a venue I really enjoy. People usually complain about the sound, which has never been a problem for me. This venue is a 10 minute walk from my mom's house so the location is great (it's smack dab in the middle of a business/residential district). It's much larger than Red Rocks (almost 18k vs. 9.5k) and has a great GA lawn, as well as an awesome front pit. They have an earlier curfew due its location, which has caused some headlining sets to get cut short over the years. But shows also usually start earlier. Honestly, if I were able to choose, I would probably always pick the Ogden for smaller shows and Fiddler's for the big ones, just out of preference.
