25g rimless cube or 34g solana HELP

[Reef23]

I recently sold my complete 140g custom miracles setup. My original plan was to get out of the hobby completely or at least take a year or so off. I have two young kids and a job that takes up 99% of my time.
After only a month or so I have decided to get back in (wife and I miss the tank) but keep it very simple. I have always wanted a rimless cube and decided that's what I will get. I now have the option to pickup a 34g Solana AIO tank (20x20x20) or a starphire miracles 25g cube (18x18x18) with glass-holes.com overflow. Both tanks are in great shape. At first it was a no brainer for me as I love the Solana's but slowly I started worrying about the limited options for skimmers and such in a sumpless system like the Solana's.
I was hoping some of you on here can help me out if you have ran an AIO setup before. How did it perform ? With the 25g system I would be able to run a better skimmer and if issues arise down the road I could run a reactor with biopellets or other such media. Keep in mind I'm trying to stay simple.
I guess another extremely important fact is I will be just housing 2 designer clowns and 2 or 3 other small fish like a helfrichi firefish. Coral wise I will be sticking with LPS and softies. I don't plan on overstocking just adding enough coral to make some colors pop.
Lighting for this setup will be strictly LED. So far I'm thinking of going with the maxspect razor for the Solana and the AI nano for the 25g cube.
Im thinking the 25G cube may have about the same room for aquascaping because it wont have the false wall like the Solana that takes up nearly 4" of the aquarium making it around 20x16x20.

Let me know everyone's opinion......

Thanks
