Interrail this summer: worth it, or just buy single tickets?

Planning a 3 weeks trip through central Europe in July with a friend, mostly cities with good museums and old architecture. I keep doing the math on a rail pass vs buying tickets one by one and the answer changes every time I look.

For people who did it: did the pass save you money, or did seat reservation fees eat everything? And is it actually more flexible in high season, when trains are full anyway?
