Outside of monitoring, you'd want a service that offers reports too. EQ, as far as I know, does not offer that. They do have a 3-in-1 monitoring for about $15, but you don't get to see your reports. TU offers TC, and I like it. EX offers creditchecktotal for all 3. I don't think EQ offers a 3-in-1 report service. Then there are 3rd parties out there like Amex's service (credit secure?) or Chase's CMS (forgot that name too, a bit slow today, need coffee).
TC seems favored for their layout. For the most part, they don't show the full history, but will show some dates, will list out late tallies, balances, contact info, etc. They aren't too bad. And you can update your reports once every 24 hrs. Also there seems to be a coupon code somewhere for $10 per month or something like that via google I guess.
Rambled too much, but you want something that monitors and allows you to pull all 3 reports.
