I have both of the all steel Ruger 1911's; the 5" full size model, and the 3/4" shorter, CMD. Both are first rate 1911's, comparable in every way to the Colts costing hundreds more. I've owned more than a half dozen Colts over the years, spent hundreds on match grade bushing/bbl. assemblies (Wilson) and had them fitted out by good gunsmiths. But those Rugers flat out astounded me with their reliability and accuracy. I'm getting groups that average 2" or better at 25 yds with 200 gr LSWC's and a moderate dose of Win 231. Their only drawback is their weight, great for a range gun, but on the heavy side for daily carry.
With all the LW version's great features, plus the titanium insert in the feed ramp area, als well as Ruger's sterling reputation for customer service, I'd jump on the LW. For carry it beats the heavier versions by quite a margin and the only draw back I can see in your future is for the various shooting games (IDPA) etc. that have very high round counts. In my opinion, an all steel frame is better suited for a gun which is used for thousands of rounds a year.
