I use both...my opinion:

eQuest:
 * Great for fast energy estimating...forget about bin calculations
 * Fast/Easy input.  Not much control of room/zone inputs.
 * Great looking output reports
 * Good if you know DOE 2.2 because you can edit in detailed mode
 * Not much good for calculating room/zone loads, sizing equipment
 * Seems to be targeted to people with less simulation experience
 
Trace:
 * Excellent mechanical equipment simulation (especially Trane equipment)
 * Good alternative analysis for mechanical measures
 * Total control of all room/zone characteristics (envelope, 
ventilation, schedules, etc.)
 * Room/Zone input is slow but excellent for calulating room/zone loads 
and sizing equipment
 * Superb telephone support from Trane
 * Seems to be targeted to Energy and Engineering professionals

Trace is a favorite of firms that do HVAC engineering because it can 
also be used for load calculations. However, models derived from Trace 
load calulations are usually to detailed for energy estimating.  Models 
become too complex and slow to calculate results.
