I'd rather have Lambo than Sark because he wasn't a constant embarrassment off the field.
I think Lambo was a slighty better recruiter. He couldn't recruit skill guys to save his life but he did bring in DL/OL/LB's while Sark was a good skill recruiter but not a OL/DL/LB's recruiter.
As a gameday coach both were equally shitty. Throw inside the 10 yard line, plunger raped on the road in big games, lose to shitty opponents, pretty solid at home but shitty on the road.
Lambo is really overrated by Doogs(hi Fleenor!) because they look at his W-L% . They assume he got a raw deal but the program was slipping under his watch and his W-L% is boosted due to having so much talent. His W-L% would been similar to Sark's had he took over at any other point in his career or if UW allowed him to continue to coach.
