If you could wait for the new accord before you purchase I'd say do that and then compare the new model.
If your going to get something sooner than later, I'd take the TSX over the Accord personally. I'd want to get the 5spd TSX and throw on the basic boltons and hondata reflash and bump the power up to a respectable notch and it would be a fun ride. Of course I'm about a year or 2 from getting a newer vehicle. I have driven the automatic TSX and I was really impressed with the power and handling. Now keep in mind I drive a 5spd 4cyl accord now so thats why I think it was decent power wise. for commuting purposes I think its the perfect car, great looking, gets decent milage, handles well, and has enough get up and go for lane changes and highway crusing. I think the Accord and the TL are a little to big for my taste, I kind of want something a little nimble and agile for some fun backroad driving every now and then.
