Are Vertical towers worth it?

I am currently planning a small hydroponic green house, I'm looking to grow strawberries, lettuce etc in a vertical tower and then use an autopot system for tomatoes and runner beans.

I was thinking about a stacking kratky method tower but the vertical towers are less than £100 and looks easier to maintain once set up.

But are they just a gimmick and require an upgraded pump to make them work?

Any advice would be appreciated
