Go for it. The newer vinyl may last longer over time and be more maintenance free but wood ones have been around, rotted, and fallen off of houses for a long time. It boils down to proper maintenance.
Get cedar, redwood, or any kind of wood as long as you prime it and keep it painted. The advice from the home cheapo/lowest/paymore clerk/stockboy who was there after high school may be based on what they sell and promote. People still buy wood siding even though vinyl is available.
