In short again - I recommend avoiding Tustin/The District and focusing on Irvine.
I can't comment on District/Columbus Grove|Square, but we've owned in Tustin Ranch and I wouldn't hesitate to recommend it -- but for a buyer that meets a profile (wants bigger house, gated is important, don't care about HOA amenities, etc).
The OP needs to provide more color on what she is looking for in a neighborhood.
So far we know Walkability and a view don't matter, CV is too close to the 5 and PS stinks. That leaves a lot of ground to cover. Does she want a younger vibe? Does she have preferences on the surrounding demographics? More/less Asian? Proximity to her job (apparently) near the District? Is there another area you've driven through that you REALLY like? Attached/detached important to you? Proximity to trails matter for walking/jogging/biking/hiking? Do you care about schools or not? Do you want a gate? Do you want a community pool? Spa?
As an example, Westpark has community pools, but few/no spas. For some, their nightly ritual involves hitting the spa. For others that jog, being close to a trail is meaningful - so we'd recommend communities that have that access.
Give us more so we can give you more. 8)
