both are good, but lack the ability to run up "more" fuel than the POS can hold.
e.g. 30 days of fuel at 100% utilisation takes at least one refuel due to space limitations in the tower's fuel hold. I think the max for a large tower is like 3 weeks and a day... Yeah, you can set them to 2 weeks/15 days and double everything; but if you're running a lot of different builds it can get tedious.
So I couple their "test build" capabilities with Dedaf's tool (prior to that, a **** spreadsheet I made myself). Just needed to change the CPU/PG usage, and they'd give the material needs. Dedaf's will even point out how many m3 you're using.
