1. I love the gotoh 510s. But you can put those on any guitar so don't make that your decision maker unless it's a real dead heat and that's the tie breaker.
2. The 810 is a great guit, esp from 2011, and that it is an LTD means it's got special other appointments/wood choices not regularly on the menu. Which Baggs system as they have some old models that were good for the day but now passe. If it's an Anthem or Anthem SL, then these are genuinely good and gig worthy. This series 810 will likely be most in the tonal family of your 414, albeit with bigger bottom and thicker-sounding mids. And it is this thicker, more forward mids-voice of the
pre-Powers DNs that I prefer, so this gives you an idea of my tonal bias.
3. The GP guitars have their own thing going on: you like it enough, or you stick to their DNs. I like the GPs, but not enough to unseat my superb DNs. I've yet to meet a GP that was better than my '08 DN, so that's my preference, which may not be yours. But heck, you asked!

4. Taylors don't have any inherent "issues" or years or model "to avoid" so no worries there.
