I think the new macro looks pretty cool. I think it's features make it a lens you could have fun with. Don't expect the light to be very strong though. From the few images I've seen it's more of a fill light. Very cool though. As mentioned earlier, the ef-s won't work on FF bodies so if your friend has plans on moving up to FF, your gift will be of no use any longer though.
However, the 35f2IS can be used on both, adds a stop of light gathering ability(a big plus for APS-C sensors), tracks very well in AI servo(I always rely on it during the processionals during weddings) AND accepts extension tubes. 12 II tube will give you .60x(more than half sized) and is fairly cheap(especially used) and extremely small. I use that combo for ring shots during weddings.
I absolutely love my 35f2IS but I know the two options both have some benefits. I really don't think either one would be a bad purchase.
These two images are what I had available. Take into consideration they're combo shots and not full rez. They're sharp! Take them more as what you can get at about half sized. For something that can fit in a shirt pocket and takes 5 sec to put on/take off it was perfect for me.
