Wordmark is always great and has a long life span. I love it too. If you may check my portfolio, you may find Regex that I've just won few days later. That's look great, very simple but meaningful for software security company where their business stand.
However, your old logo that used 7 'swoosh' is look different and I already like even when I looked at it the first time (not its center design included). So I recommended to keep the '7 swoosh' in your new logo. And that's good I think to keep related with your past, right?
LEADER is eye-catching word. Inspiring everyone who see it. That's the reason I make it look dominant then other words. I glad it look like work for you, too.
Thank you for your feedback, and sorry for not respond faster, just because its 4 am now in Indonesia :).
