Quite a bit for me but it depends on how you hit the ball.  I have a gap between my 3 wood and 3 hybrid that I am trying to fill (250 and 210 yards) I assume you're doing the same thing.  I hit the wood much farther than the hybrid.  I find the low loft hybrid harder to hit than the high loft wood.  I'm right now shopping for a 5 wood and plan to replace my 50 and 54 wedges with a 52....we'll see how that goes. I may decide my scoring is more affected by my wedges but it seems I've been between the hybrid and the 3 wood approaching par 5's a lot lately.

Get fit and hit them both.

I personally find a 5 wood or a 7 wood MUCH easier to hit vs a 19 hybrid. The 7 wood has 2 degrees more loft and gets 5-10 yards more vs a 3 iron hybrid. I've been a big fan of the 7 wood since about 2006. You can use them from a wide variety of lies. They are pretty accurate and are great for longer par 3s. Shaft length is manageable (generally between 41-42"). Lie angles vary little between vendors (generally 57.5 to 58.5 deg isn't too flat). They are very workable. They are almost impossible to miss with. There is one thing that a 7 wood has over a 3H: the "knock the crap out of it" factor. You'll see that 7 wood usage is more prevalent among Champions' Tour and LPGA pros but there are a few here and there in the PGA that carry a 7 wood (and there are a few Champions' Tour players that use X flex shafts). Gary Player even carries a 9 wood in his bag and lamented that he would have won one more Masters had he had one.

I think the difference is that the wood has a bigger club head and that creates more momentum on the downswing, which makes the ball go farther. The wood is also easier to control.
