Hi Biagio,

I face this dilemma too!  For me, questions to ask yourself are:

* What are your timescales? When is your deadline? ... if it's tight, then go v4 - it is a stable solution!

* Do you rely on 3rd-party packages? (e.g. uComponents) ... then go v4.  (There is no uComponents for v5)

* If you have the luxury of time and learning a new technology ... then go v5!  (More exciting than v4, but prepare for some rough edges)

Cheers, Lee

We're working on a section on umbraco.com to provide guidance of whether you should choose v4 or v5 mostly in line with the points of view from Lee above.

Rule of thumb atm - if in doubt, you should go with v4. More details to follow.

Hi, thanks at all.

I think that I'll go with v4 for this project, because the prj is very large and upgrade in the future to v5. 

I'll use v5 for other two small site , so I have more time to study it.

Having recently spent two days with v5 doing Level 1 training, I have no hesitation in saying stick with v4.  Right now, v5 (specifically, we were using 5.1RC) is just not ready for production use; I'd love to say it is, but to build the average site, that you need to work, then v5 just isn't there (yet) - both because of bugs and missing features.

Hi Biago,

On the Dutch Umbraco Festival 2012 last week, Niels Hartvig said in his keynote speech that there would come a page with criteria when to choose Umbraco V5 or when to choose Umbraco V4

greetings,

Anthony
