Both these bikes are low grade on specification and if you intend to use them for serious use they will cause you a few problems. Saying that- 20 years ago I had bikes running Tourney and Altus deraillers and They lasted for a couple of years but they never gave a good ride and a lot of walking up the hills. Those bikes were heavy.

Don't know how much they are going to cost but I do feel that with the low grade of these bikes -you could do a lot better by looking secondhand.
