Out of the choices you have listed I'm gonna go with TSX...

Here's my reasoning...the RSX is a coupe and I prefer 4 doors ( you may not). The Accord is a great sedan but tends to isolate the driver from damn near everything, however, you can get a powerful V6. The TSX gets good mileage even if you drive it hard (from what I've read) and is one of the best front drivers on the market. Evidently a simple tire change breathes new life into the handling of the TSX...
