Test is test. The best ester length depends on what you're able to tolerate in terms of injection frequency. It may be partially psychological, but it seems that some people differ in their ability to "feel it" depending on how many times they inject a week.
Myself, I like to shoot EOD. When I'm backing off the injections because of scar tissue and the sheer annoyance of constant pinning, I do it every two days with a longer ester or even Sustanon. I still feel it. But I swear, even if I tried to lose the bias and chalk it up to placebo, I really do feel much more when shooting EOD. I've tried my best to convince myself that it's placebo but I really feel more.
