Difficult The wood one is lovely - and I prefer it personally - but I'd go with the zoozone. I once emailed the makers of these to see what wood they were made of and they said cedar. Now I know that's not the same as cedar shavings, but I still wouldn't fancy using cedar wood for a hammy. There are some similar ones that are made of pine, but they aren't so big.
Aside from that you'd need to be prepared to do some sanding - it could have splinters especially as it says factory seconds, and then plastikoting inside probably.
This is the one made of pine (fir) - it tells you further down. But it's more expensive and the 115cm width is the maximum width but it's still a great size. Someone else on here has one of these, and when you assemble it you can swap the bottom door with the top panel so you can fill the base with substrate and have a front opening access door

I nearly got one of these but wanted to stick with a cage as that was what Charlie was used to - plus I didn't fancy all the painting lol.

I think a Robo would be very happy in a Zoozone 2 as long as there was lots of cover, like a platform and lots of tunnels and hidey places and not too exposed from above. The advantage of the wood ones is the shelves I guess, but then the cons would be watching out for fall risks with a little robo. It would need setting up carefully in case they jumped off the top shelf onto something. On the other hand if you swapped the door to the top you could get masses of substrate in their and that would reduce the height a bit, give two shelves and loads of tunneling area.
So if the second wood one wasn't too expensive I'd go for that over a zoozone 2, but not the Tectake one personally.
