I find the ceramics to be really good value for money, with two caveats:
1. Not all sockets fit all brands (my advice would be to buy one bulb and test before buying a stack of them).
2. Some of the cheaper brands are really shoddy and only last a few weeks
After saying that, if you keep herps in your bedroom, the ceramic heat emitters are a must (unless you use heatcords / heatmats), as coloured globes will drive you barmy (especially during winter, when they are on most of the time). In fact, the only real downside is that it can be hard to tell when they have blown.
