Best place to build large/complex settlement?

[rhn]

I ended up using Hangman's with the suggested mods as my main settlement. It is built in institute theme, sort of RP'ed as an institute outreach/trading/research aboveground hub.
It worked out really well I think, but still WIP. The interior of the buildings were perfect for Interior plots. I built an institute "shell" inside the buildings for cleaner look, as well as RP'ing that the institute made them air-tight for safety/health.
The alley was a lot of fun to dot with buildings and bridge them all together from street level up to the rooftops. Rooftops are perfect for vertibird pad, greenhouse, research lab and penthouse. Settler pathing is a bit meh on the walkways. But aesthetics won over usability.
So far it holds 27 settlers, all with residential and work plots. I probably wont add any more. I mostly used interior plots, but did make room for 4 Advanced Industrial plots: Remelter, Newspaper, Magazine press and still to upgrade Glass Blower->Observatory(might change this).

@rhn: That is freaking incredible!

Would you consider exporting that with Transfer Settlements?

I'd really like to study how you did all that.

Damn... that is one hell of a build. I love the clean look of the white institute walls with the food stations.... Oh man the wheels are turning.

Back for another playthrough of Fallout 4, and I thought I would try and avoid my usual problem this time. I usually end up expanding Sanctuary a LOT and build a huge settlement on Spectacle. Both often end up causing a world of problems. Sanctuary due to the triangle of CTD, spectacle because it being multiple cells(and too much room for me to go nuts).
So what is the best place in the game to build my large "main" settlement for performance and reduction of issues? Should have space for several IR plots.

Any building in sanctuary in the back at the circle?
