Let stick to 1 NXT = 1 VOTE. That is the simpler approach and it seem fair to begin with.
Let's not. Let's try and find a solution, instead of just giving up.
1 NXT = 1 VOTE is the cleanest soluation. Not sure why people doubt that. All other approaches with account caps (e.g. one account can have a maximum of x votes) can be manipulated by creating mulitple accounts. And the more complicated it gets, the more are people discouraged to vote in the first place.
And of course small account holders will criticize this approach and thats totally natural, but i have a only a few nxt too and still think that people who invested in the project in the first place should have a bigger saying.
