I have use TaxAct for several years, for reasons similar to the OP. I'm also not a big fan of Intuit's business practices, so I avoid them where possible.
On filing, I generally get a (small) refund so I file electronically to get my money ASAP. However, when I do something big like selling a bunch of stock, I'll file with paper and as late as possible. Gives me more time with my money, and rumor has it you're less likely to get audited with a paper return. Don't know if it's true, but doesn't hurt and even a little less probable is a good thing.
