I own and use both. I only voted for the 47D because they're less expensive.
The ETMs are easier to load (not that either of them are any trouble).
The ETMs look better IMO.
I personally own 7-8 47D's and 3-4 ETMs.
Cost an issue I'd go with 47D, no cost issue go with ETM.
You wont go wrong with either, and if you do, I'll give you $20 for them.
