I don't own either, but thanks to Grizz and Mark I've seen both in use. Grizz (Jim Capozzi) has the planer, workhorse machine does a fine job. Mark has the planer, and if I weren't buying Grizz's old craftsman so he can upgrade, It would be on my short list of tools to save up for.
Contrary to Ned's typing, I have the jointer. I'm quite happy with it. I suspect this is true of all cast iron bedded jointers and not just mine, but you need to keep on top of waxing it - gets a little interesting to pass wood through it if the wax wears off. I haven't gone nuts with dial indicators or anything, but it is easy to adjust the fence both laterally and for angled edge jointing. The pivot pin for the guard is kind of a pain to remove and reinstall, but I can't imagine a way to have it set up to be less a pain and still suitable for its purpose. You only take the guard off for rabbets or jointing wider than 6" boards.
I've had the occasion to use the jointer for rabbets and for angled edge jointing. Both of these operations went well, except that 1 out of 8 rabbets I did for my cherry floor thresholds was difficult to push and I don't know why. I don't think this was a machine issue but some sort of operator issue.
Speaking of rabbetting, the jointer has a stop that requires you to pull out a knob to allow for greater than 1/8" depth of cut. Unfortunately, the machine does not have a stop to prevent you from leaving it at 1/4" depth of cut after making a rabbet and forgetting to check cut depth the next time you're trying to flatten a board.
Not sure any jointer on the market has this feature though. Work too hard to prevent operator stupidity and you wind up with headless hammers missing a handle too.
I haven't used other jointers to compare to, but one of my buddies in the area started on this model (before upgrading to an 8" unit) and this seems to be a very popular first jointer for folks. I put mine on a custom mobile base together with my drill press, but I have a kind of unique shop set up. If you have a part wall in your shop, you can orient the jointer like the take-off deck of an aircraft carrier and buy yourself a little extra space / not have to move stuff out of the way of the jointer path for longer than expected boards.
Keep up with the DC when using this guy. The port tends to clog if you decide to not run the DC for some odd reason like the bag fell off and you can't be bothered to put it back on.
Hope this helps!
