MDF is is very easy to cut but is tough on edge life. The triple chip grind is the most durable, so is a good choice for MDF. If all else is equal, more teeth would leave a smoother cut but will have more resistance….fewer teeth will tend to cut faster with a rougher cut. Somewhere between 30T and 60T should work fine, and even an 80T would work. Find a deal on a good one and go with it.
