I have a galaxy, space wise it gives us what we need. We have plenty of room for 4 dc's, including one yr old twins with bulky car seats. We have a graco duo sport which fits behind the seats so although not a huge boot it does what we need Downside of ours is petrol engine, I blame the fact I was 38 weeks gone with the twins when I bought it! Running cost are high with regards fuel & road tax. A diesel would have been better That said my insurance is pretty cheap
I preferred the Touran but the galaxy is bigger and back seats are better IMO.
I have a grand Picasso, enough room for 3 car seats and a big boot or two extra seats. My DCs are 8, 6 and 2 so we have 2 seats and a booster, but that is on one side not in the middle. Mine is diesel and does about 350 miles on about £60, but that includes traffic on the school run.
I would, easy to drive and park, lots of room, economical to run (I have a diesel 1.9) very versatile - all the rear seats can be removed if a huge boot is needed. Mine is a 2001 and has a VW engine despite having a Ford badge! I love it
We have one of the newer Galaxies (2006+) and it's great. If you can stretch to one with parking sensors it makes it waay easier to get into smaller spaces . We luffs ours (especially the flexibillity of the foldflat seats and the large boot when you're not using all seven seats). Oh and yes, get a diesel! (no left pulling issues with ours BTW)
