ive been using a 100' roll of delta 400 this year and it blows.. it does fine if the scene in the view finder is extremely well light up and bright.. put the meter on the bright spot and it works great. but put the meter on a shadow or dark surface, and your suddenly under exposed horribly, often times into as if the negative was dipped into thin blak paint.
ive used DD-x and rodinal and rodinal gives better results and for a whole lot less, but the light issue is still there.
Please consider that your camera meter is designed to be accurate only on scenes of about 18% reflectance. Meter an appropriate gray balance target such as a Delta-1 Gray Card or a One Shot Digital Calibration Target (surprise, it works for film exposure, too!) or use an ExpoDisc "filter" over your lens to average the light falling on the scene (by pointing at the light SOURCE).
Pointing a camera meter at white will underexpose by more than two stops. Pointing it at black will overexpose by more than two stops. Pointing it at 18% gray (or an average day-lit scene containing blue sky, green grass, and other foliage) will yield good exposures.
Use a developer designed for tabular-grain films when processing Delta 400 or T-Max films.
Follow the manufacturer's recommendations for developer, time, temp, and agitation styles. Otherwise:

Film has much better highlight latitude. With digital, once you saturate the sensor with photons, there is no recoverable detail in the highlights. With film, highlight overexposure by almost three stops is often recoverable. It's a pain with more than a stop and a half overexposure, and results are less than optimal, but it can be done.
If print highlights are plugging up (negatives are too dense) when your exposure is spot on according to a gray card or incident meter, then reduce film development time slightly. Alternatively, try a "compensating" developer.
If you really want to "get jiggy wid it", study the zone system. Otherwise, a gray reference is mighty handy!
