debugging of complex 64b targets and proper tools

[arlequim]

Ok, i admit you will never like the WinDBG because of its interface and the vast array of commands , but it's surely the most powerful debugger out there for ring0/ring3 debugging. Moreover it can handle tons of stuff that no other debugger can do for you right now, at least under x64 platform until "SoftIce64" will be available Think about this, i am sure it is the best choice, thats why i am spending a bit of time every day to learn it in depth. As for direct patching, Hiew, no doubt

WinDBG is definitely the best option in my experience. You should be able to use the WinDbg engine in IDA now I think as well. WinDbg isn't too bad to get use to, and its powerful and scriptable. Debugging services is simple too, you can set your target to execute in WinDbg when the service starts: http://support.microsoft.com/kb/824344
