Here's a really good article that explains what you need to know if you're thinking of a wall-mounted faucet: http://www.homethangs.com/blog/2014/03/installing-a-wall-mounted-faucet-and-why-your-contractor-doesnt-want-to/

There's no right one or wrong one but there are things to consider. You really have to think about who will be using the sink. The wall mounted may be hard to reach if children are gonna be using this bathroom. Also, the wall mounted faucet you have shown have knobs. May be hard for older individuals to use this as well.

Thanks so much. Great article. Now I understand why my husband is pressuring me to choose faucets when home is only in framing stage. There has to be special things plumbers and builders do to prepare. I told him I'm choosing tile and sink before faucet. He's getting pressured by his plumber. Now I understand. I never knew about history of wall mount. Ugh. Too many choices !
