Given the choice I'd go for the H9.
I sold my H5 to buy a H9 and was offered my H5 back as the person who bought it then thought it was a bit big for them. Worried about the reviews on the H9 IQ, I was I was actually going to buy it back but in the mean time took more photos with the H9 and saw no real problems with them. IMO, the IQ seems no worse than H5 images and no better either. Both take great shots and both take bad shots to (probably more so with me as I'm a novice). You can look at many H9 shots and convince yourself that the camera is bad but then I look at my bad H5 shots from the past year and think, "hello, that used to take shots like this to" but I never worried about those as I wasn't in a forum where folks were bashing the H5.
For me the things I love about the H9 is it's sheer speed over the H5 in focusing, burst speed and normal operation, the tilting screen, better flash, the colours of the images and the remote control. The latter is superb when the camera is on a tripod and you can just control it from the remote.
Downsides of the H9 for me (not really downsides just personal preferences really as I willl learn to live with these), well being a novice and needing to learn about how to use manual modes, I still use scene modes and Sports mode is a bit dissappointing, not sure about the huge flower lens thing on the front and I preferred the thumbwheel on the front rather than at the back.
The reason I didn't buy back my H5 was because I made a list of all the things that the H5 had over the H9 that I thought I would need.
According to comments - better IQ. That was it.
I then realised if I had my H5 back, I would never have used it as I'd always take the H9 out - so why buy it? So I didn't and I put the money into a tele and wide angle lens for the H9. Regrets - non at all.
I have had some shots from the H9, both macro and scenic that I really like and they have printed amazingly well at A4 size (8x11). That's all I need a camera for and so for me, the H9 is superb ... but having said that I think I will need to learn more about the manual modes as the H9 isn't as good in auto modes as the H5 was - I think that was more novice friendly. That isn't a bad thing though as I'm excited about learning P,A,S and M mode.
These are some of my H9 shots. I have the colours in P mode set to Vivid as I like that.
