I need to make a new website and i have some doubts about which environment is better, i mean, i am thinking about this two differents environments:

1) HTML+Javascript (jQuery) and, from client side, make call to a webservice in .net

2) Classic ASP.NET (Ajax + jQuery) website

My strongest skills are .Net (C#) and javascript, i don't want to use MVC, what do you think which is better?

Do you have a better suggestion for make a website with .Net (without MVC please)?

Thanks a lot for your help!
