We moved to Profoto years ago and would never go back to 'below' them or say Bron. The build quality, reliability, consistency, strong light mount and stand mounts, etc - all the usual superlatives you hear about higher-end lights.
We have some B1s and D1s among our gear and their great units, but do p/u domes. They make a diff in large soft boxes, and in BDs.
Also consider Acute packs. We have 3 and love them. Due to the B1, the price had fallen out of the bottom of the AcuteB series in the aftermarket and 1200 packs are no longer sexy.
The pack and head system, regardless if Profoto or Bron, really opens up the ease of use with many mods, like any future paras and makes for safer booming. In addition, the Acute and Pro heads have the umbrella holes alongside the tube, so would can turn any Para or octa into a BD using an Eli defector kit - or Eli rod with a Mola perforated deflector.
