If you have a job offer at hand, you might be better off applying as a skilled worker right now. This is simply because applying for a TechNation visa needs a separate set of documents that you need to pursue and then there is the uncertainty of the outcome. However, with a skilled worked visa, the application process is relatively straight forward (your company’s lawyers will take care of it) and the outcome is also relatively on expected lines.
You can always switch to TechNation visa at a later date and enjoy the benefits that come with TechNation visa. The ILR eligibility for residence is accrued even in Tier 2, which means even if you apply for your TechNation visa and get it, the total time to ILR will be no more than 3 years from when you enter UK.
Of course, there is always a risk with this approach - what if TechNation visa ceases to exist? or the 3 year ILR eligibility changes? or the criteria changes? Any of these things could change in future, leaving you either better off or worse off than applying today.
On the other hand, if all your TechNation visa paperwork (i.e. evidences and LoR) is almost ready, you can potentially apply for the endorsement right away and get the response soon enough and you can enter on a TechNation visa itself.
Hope this gives you a balanced approach.
