There's a lot to consider, and it's more than just the active elements. You want to also consider the topology: Single-Ended, Push-Pull, Ultralinear, Parafeed, etc. Also consider where feedback is used and how much. Do some searches here or just peruse this forum and you'll find a lot of discussions on these topics.
