First, [welcome] to the FOG!
Personally, I wouldn't want a combo planer/jointer.
I have a Jet JPM-13 planer/molder on the closed stand I use to plane large, long rough stock. The large units, no matter how well you set them up, will usually leave snipe at both ends of the board, at least that has been my experience. Also, the larger units when planing, the head is stationary and the table moves up and down. This means always having to adjust your infeed and outfeed supports......
For smaller boards or to dimension stock to a certain thickness, I will always go to my little Ridgid 13" planer. On the smaller "bench top type planers, the table stays stationary and the cutter head moves up and down, thus, once you've set up your infeed and outfeeds, no more adjusting required....
The knifes on the Ridgid seem to last forever, but the best feature of the Ridgid is what they call a "Sure Cut" lock down that prevents movement of the cutter head. This virtually eliminates snipe, and coupled with my custom made infeed and outfeed set-up, I never have snipe. I think there are a few brands out there with a similar feature, and I wouldn't want a planer without the head lock...
I would probably go for the smaller unit if only were to buy one. Only draw back for the smaller units, the motor is VERY loud!!!
Don't know if this helps, but I've found it to be a quite useful arrangement.
