I've used PT, but never really for durm editing. What exactly is it that you find so simple about it compared to other DAWs? Once again, Sonar might be the ticket.
The great thing about drum editing with PT is this:
-You group the drums.
-You select the drum section you want to edit.
-Hit ctrl + numpad 8.
This brings up (ideally) the only window you will need for the entire process.
From here you:
-Hit 'capture selection'
-Select which note values are contained within.
From here you:
-Select 'Region Separation'
-Set resolution to 'Sub-beats'
-Set desired Analysis method.
-Set Sensitivity
-Hit Separate
Now you have all the drums split at the appropriate transients, after going through what are 5 entirely logical processes, ALL contained within the one window. Awesome.
From here you:
-Select 'Region Conform'
-Select your desired 'Strength' rating
-Hit Conform
Now your drums have been quantized to the grid. Super!
Now:
-Go to 'Edit Smoothing'
-Select 'Fill and Crossfade'
-Select 3 to 5ms.
-Hit Smooth.
At this point, if your drummer isn't a piece of shit and your recording has been captured with a good amount of separation, that's it. Your drum editing for that section is done. All done within one little window with 3 tabs on the side. If something has fucked up, it's usually a fairly simple matter of getting up in there and fixing it up manually with the smart tool and assortment of keyboard shortcuts at your disposal.
The amazing thing is that the new Elastic Audio is even quicker and easier to use than that. The drawback is that it sounds like shit. If they ever get that sorted, they will have something to supersede Beat Detective, whilst all the other DAWs are still trying to match it...
