Not exactly. If I had unlimited room and could afford 12" separates I would probably go that route. I don't so I went with the combo machine and for the most part have been happy with it. I bought the separate planner becuase it has a Shelix head and was actually relatively cheap at under $1K I wanted to see if I thought the Shelix head was worth all the hype given the Tersa straight blades in the Hammer are so good, it is but the Tersa knives are great the shelix is just better. The negative about a combo is switching over but as long as you plan your workout its fine. If you miss a board or have to redu one its a bit of a pain. this is where the 12" Oliver comes to play for me I also find myself using it on curly or figured wood for small boxes etc. I have less the $5K total into both machines and you simply can't buy separates for that price, period. You also can't fit them into the space that these fit into. I have had the Hammer for about 15-17 yrs ish don't remember exactly have used 4 sets of knives, and replaced a capacitor ($35) and it has been dead accurate with no adjustments in that time. I know folks will say you don't need a 12" jointer but I use boards wider then 8" on a regular basis and would never go back to a jointer less than 12". I also hear about the short bed argument and will just say outside of my Roubo bench build it has never been an issue I felt that needed to be addressed.
I think the new Hammer folds straight back and that would be awesome for space, mine is like bat wings and takes more room.
Bottom line for me and my shop I would go with the same setup again without any concern. If I was to upgrade it would be to the Felder AD 951 but its like 2.5 times the cost and honestly I just can't justify it and trust me I have tried LOL.
