Nope... Everything I brew goes to keg when it's ready for carbonation and then going to glass. BUT, I do give bigger beers time to age before transferring them to serving kegs. I have a (12.5%) wee heavy that I made in December of 2011 that was kegged in December of 2012 and has been sitting on the gas carbonating in the basement. I plan on pulling a glass of it soon. I also have an old ale (8.9%) that was brewed in March of 2012 that was kegged the same day as the wee heavy. The wee heavy had been sitting on oak cubes for several months, and the old ale was sitting on a section of medium toast cherry wood for almost as long.
IMO/IME, kegging is better provided you give the brew enough time to do what it needs first. Kegging is better since you have complete control over the carbonation level of the brew. If you want low carbonation, you use less pressure/CO2. If you want to increase it after you sample it (after a few weeks) then you can give it more pressure. If it's too high, you can bleed off pressure and then lock it in where you really like it. With bottles, you pray that it carbonates to where you think it will and hope that it won't take several months to get there.
