I've never heard of GMAT+, so I can't tell you whether it's a good source. If the "paper based test" source you're talking about is official paper-based tests, then those are better questions than non-official sources.
There are even better questions than the official paper-based test questions though - the official CAT-based questions. The most recent publications (Official Guide 12th edition and the Quantitative and Verbal Supplements) contain 1,500 questions between them. OG11 has an additional 300 questions (approx) that don't appear in OG12. There's also GMAT Focus, a quant-only online diagnostic test that again consists of more recently published official questions. Unless and until you've exhausted the most recent questions, I wouldn't go for questions that are 12+ years old (the last paper-based test was given in 1997).
And, really - nobody needs more than the most recent official questions - we're talking 2,000 questions among the above recent sources I listed. If you aren't studying the best 1,000 or 1,500 or 2,000 questions in the right way, then doing another 500 or 1,000 lower-quality questions isn't going to do much for you. This isn't about volume - it's about the highest-quality study you can do with a (reasonable-sized) pool of the best available practice questions. So keep that in mind as you decide what to use!
