I use the Coloplast Sensura Flex system and am quite happy with it. They had started me with the Hollister in hospital, but the tape would stick too well to my skin, so I tried the Coloplast and am quite happy with it. It takes less time to put on then the Hollister, and the bags is broader than the Hollister, so there seems to be a better distribution of the output. With the Hollister, I always felt like I was carrying a tennis ball the minute it got a quarter full.
Since I started with the Coloplast, I've also not had any leaks/blowouts at night and can often sleep for about 7-8 hours without emptying.
