Some houses provide more bonus per rank and cost much less points but have a bit lower maximum bonus, e.g. Vidar Polar Coil grants 8.5% more heat capacity and costs 2 points at base but can only get up to 42.5% capacity on a lvl 3 slot while Zekti's grants only 6% and will costs 4 points but can be ranked up to 11 points and 66% bonus capacity.

So, yeah, 3 points/42.5% bonus vs 11 points/66% bonus. You can choose which stat to focus on while not losing much on the other one.
