I'm considering going career with the army. Would it be better to go through ROTC or try my luck at a military college?

Al, the term "military college" can be misleading.

One obtains a commission through one of several channels. Coming out of high school, one can apply for an ROTC scholarship, or take ROTC with hopes of being "invited" to continue on towards a commission. Many "military colleges" offer ROTC programs of course. Another route (the one I took) is to apply for acceptance to a federal service academy (West Point, Colorado Springs, Annapolis, King's Point) and pursue the adjoining congressional, senatorial, VP or presidential appointment (you have to get both). Complete four years at one of those, and you graduate an O-1.

Yet another route is OCS. If you have a degree, this is usual path. Plenty of enlisted people come up this way as well. There are other more complicated routes...or simpler, depending on one's point of view; direct commission (pretty much just docs and lawyers), limited duty officer (usually fairly senior enlisted subject matter experts) and warrant officers (also generally SMEs, though I believe the Army has younger warrant officer aviators).

There are "military" schools which pattern themselves after the academies, and may have "connections" that aid in applicants obtaining ROTC or even Academy appointments...but some merely offer a "military style" education.

I got my Congressional nomination to West Point from Rod Blagojevich, who is in prison. Chicago/Illinois politicians tend to pass through prison regularly... ;-)

A little more background on options.
Under current law, there are three types of ROTC programs administered, each with a different element.
The first are the programs at the six senior military colleges (University of North Georgia, Dahlonega, Georgia; Norwich University, Northfield, Vermont; Texas A&M University, College Station, Texas; The Citadel; Charleston, South Carolina; Virginia Military Institute, Lexington, Virginia; Virginia Polytechnic Institute and State University (Virginia Tech), Blacksburg, Virginia), also known as military schools. These institutions grant baccalaureate degrees (at a minimum) and organize all or some of their students into a corps of cadets under some sort of military discipline. Those participating in the cadet program must attend at least 2 years of ROTC education.
The second are programs at "civilian colleges". As defined under Army regulations, these are schools that grant baccalaureate or graduate degrees and are not operated on a military basis.
The third category is programs at military junior colleges (MJC). These are military schools that provide junior college education (typically A.S. or A.A. degree). These schools do not grant baccalaureate degrees but they meet all other requirements of military colleges (if participating in the Early Commissioning Program) and cadets are required to meet the same military standards as other schools (if enrolled in ECP), as set by Army Cadet Command. Cadets can be commissioned as second lieutenants in the Army Reserve/Army National Guard as graduating sophomores. Upon commissioning, these lieutenants are required to complete their bachelor's degree at another institution (of the lieutenant's choosing) while serving in their units. Upon receiving their bachelors, ECP lieutenants can assess active duty and go onto active duty as a first lieutenant. Only the Army currently offers an Early Commissioning Program. In time of war, MJC's have played a significant role in producing officers for the Army. During the Vietnam war, the requirement to complete one's bachelor's degree was not in effect. Therefore upon commissioning, lieutenants went straight onto active duty.
One difference between civilian colleges and the senior or junior military colleges is enrollment option in ROTC. ROTC is voluntary for students attending civilian colleges and universities. However, with few exceptions (as outlined in both Army regulations and federal law) it is required of students attending the senior and junior military colleges. Another major difference between the senior military colleges and civilian colleges is that under federal law, graduates of the SMCs are guaranteed active duty assignments if requested with the approval of the school's professor of military science.
