No one is a better judge for your tools than yourself.
In this side of ponds we have many photo stores that are renting tools. You may want to try something similar and put hand on each of these babies on two separate week ends on a similar task assignment and then see it for yourself, which one works best for you. I am still for 300mm F2.8 plus 2x mk ii TC.
