As the "Senior Member" title below my name implies I've been a WinGate fan for a long time. I do all I can to get the most out of WinGate. I'm also a critic who whines to the developers quite often about things I don't like or would like to see. I don't work for Qbik or even live in New Zealand.
I've been testing 6.0 Beta for 5 or 6 days and it's great! It has been rock solid with memory and CPU usage very well behaved.
We have web browsing for about 100 users, coroprate email for close to 400 mailboxes plus web hosting being serviced by WinGate so we work it pretty hard. 6.0 has proven up to the task.
The best part of 6.0 so far has been the "Block spoofed sender Address" of the SMTP server. We're averaging about 1000 messages blocked EVERY DAY!! That's a significant time savings for folks not having to worry all that junk SPAM. So far the "false-positive" rate has been below 2% and that will be reduced futher as we configure the service.
Bottom Line - get 6.0 now! Test it out. If there are any changes you'd like or problems found post them here so the developers will know. My configuration may not be like yours so as many folks as possible need to test to get the best possible idea of how the product behaves.
The more we test the product before the release, the better the release will be!
