You never will know just how productive you are or were, and you're best just accepting that. I learned from playing poker that when the quality of your work and your results (in the short term at least) have no provable correlation, it's easy to fool yourself into believing one way or another, but in the end you can only look back and guess in hindsight.
The nice thing about programming (or writing, or tons of other creative endeavors) is that feeling you are more productive will likely actually make you more productive. If you're frustrated because your tools are holding you back, that's going to spill over into your work and make you unproductive. If you feel like you're getting things done, you're more likely to get things done later. So you just use the ones you like best, and assume you'll be more productive because they're the ones you like best.
The only time when you're certainly not productive is when you're arguing on the internet.
