I don't often comment on these threads, but my 2c, on Cartesian designs, I've built hbot, core xy, ultimaker and more conventional gantries, and I'd pick the ultimaker design for a new build.
Both Hbot and Core XY designs require a high degree of rigidity in the frame and high quality bearings to perform well IME, conversely it's hard to build a working ultimaker gantry that doesn't have close to perfect XY alignment, pretty much everything in the design forces it. I also prefer the shorter belt runs, IME in designs with long belts, you get an effect where there is a measurable difference in the way the belt responds close to the driving force of the motor and further away from it.
The ultimaker and zortrax have reputations for high quality prints for a reason.
The raise N2 version of the design mounts the extruder on the gantry and they seem to get away with it, so it doesn't require a Bowden style extruder.
I'd seriously consider a eustathios or similar design, if the plastic parts are off putting, most of them could be machined or easily modified to be.

I would not dismiss delta design too quickly. As far as I am aware only delta and light weight corexy printers can print at over 100mm/s with decent quality.
Not a Delta but mine(own design) can print also with that speed and even faster and with a very high perimeter quality.
The printer in the image is a prototype and works perfect. Busy making a larger version this very moment (heatbed 200x300mm), almost done.
For a brief moment, after I wrote that delta and corexy 'rule' , I considered Ultimaker design but overall I think it's performance sits in between speed and precision, and probably 100mm/s is too fast for good precision (especially for larger printers). Please post your results when you get your printer up - I'm curious how it works out.
That printer(I named it Ulti-Printer(The name Ultimaker was already taken... ) is already in service for a few months now. It outperforms all (about 20)printers by far we've built in the past. The perimeters are superb, no ripple at all, no ghosting around holes.
I expect the larger version I'm building right now will do the same.
