another vote for kettles
keggles are heavy and a pain to clean
I had a mess inside mine from my last batch brewed (last weekend/Saturday). I thought it was going to be a PITA to clean, but it was far from it. Even in the kitchen I have where the sink has full cabinets over it (so I cannot have the keggle over the sink) it wasn't an issue. It was rinsed before I took it home (I brew at my buddy's place currently). I took it up (out of the truck) the following day, and got to cleaning it. All I ended up needing to do was use a good scrubbing sponge (like you get in the grocery store) to get the heavy stuff off of it. Same as you would with a kettle. I used my quart measuring cup to wash down the sides, then drained via the ball valve and dip tube. Left less than a quart behind, so I just used a hand towel/sponge to remove that amount. Then rub down with a damp towel to get whatever was left. Easy (IMO) and clean. I removed the ball valve and soaked it in some PBW solution, along with the dip tube. I removed the sight tube assembly and simply ran hot water through that to clean it out.
Once I have my brew stand, I plan to use a CIP system to take care of it. That will make it even easier.
Something else to think about. Most people don't hesitate to put more holes in keggles as needed. Most of us pause to put holes in kettles (especially Blichmann kettles)...
I also just weighed my current keggle... Complete with TC fittings, dip tube, ball valve, clamps, sight tube assembly (all stainless fittings and borosilicate glass) it comes to about 35#. I transport it to my buddy's place every brew day along with my keg mash tun (it weighs less than the mash tun as they travel). I install the ball valve and sight tube when I get there, so transport weight is closer to 30#... Still, if you cannot carry 30-35# a short distance (most people won't need to do what I do) then you have other issues that need to be addressed. Or just get a proper brew stand so that you don't need to move them at all. Once I'm able, I'll have a brew stand and do CIP for the mash tun and keggle... I hope to have a tippy system for the mash tun, to make cleaning out the grains easier.
