I haven't flown the LT40, so cannot comment on it, but my favorite trainer is the Goldberg Eagle 2. I soloed very quickly when I started flying, and have to attribute a lot of that to the Eagle. It's rock solid in the air, and slows down ooh so well. Its been 10 years since I've had a trainer, but am currently building another Eagle just to have something to buzz around with for a relaxing flight, and to practice spot landings and such. The fact that my son will soon be ready to start flying is just another good reason to have one around.
