I honestly think it will be more about whats available to you more, and how much you want to spend. From your info, the tamiya acrylics may well be the way to go, as you already have them, and are obviously already used to using them. With acrylics too, ad you say, the cleanup is easier. That being said, I actually prefer the humbrol enamels. While cleanup is a little more with thinners etc, I find the finish and paint quality excellent, very available in my area in Australia, and as people have done full esb paintups with humbrol enamels, the colour lists are already out there, with far less colour testing and mixing needed. Just a couple of pros and cons, but ultimately, it will be more of a personal preference..
