I would suggest the solid aluminum pipe, however I must take an exception with both Hayzee and Pushkins on this one.
Tape the joints but do not screw the pipe together. The tips of the screws extending into the pipe would catch lint and will eventually cause a clog.
The pipe must have a slight downward pitch. (not more than 1/4" per ft.) You have to remember that the humidity of the air in that duct while the dryer is running is 100% therefore you can expect a heavy amount of condensation to form on the pipe walls. The pipe needs a slight downward pitch to permit the condensate to run out the end and not back to the dryer.
