If you are considering Tayside, I'd implore you to visit ACS at Perth. I've trained at both, ultimately finished off all my commercial training with ACS.
ACS are a much bigger school in terms of Fleet & Instructors. In my opinion the fleet at ACS is much better (3 DA42's with a DA42 sim vs 1 Seneca with a generic sim on site at tayside). The fast track course at ACS is also considerably cheaper than the Tayside Degree program. Just from the social media feeds, ACS seem to get a lot more people through commercial training than Tayside.
I'm slightly biased as I finished my training with ACS, but it was a first class school. Friendly staff and instructors, good fleet, good facilities. Call them up and request a tour/meeting with an instructor they are more than happy to facilitate.
Best of luck.
