I realized I never posted the results when I finished my side by side comparison of the Moore & Wright MWELM and the Starrett 98-12 levels 2 years ago, so here they are:
Where they are the same:
- Both levels are 12", with 3 bubble vials (1 main, 1 horizontally perpendicular and 1 vertically perpendicular), and a V-groove down the center of the main measuring surface for corners and round objects.
- Both levels arrived calibrated spot-on, and provided the same measurements (bubble offset on the same surfaces).
Differences:
Case:
- The Moore & Wright MWELM came nicely fit in a foam-cutout inside a plastic case.
- The Starrett 98-12 came in a cardboard box with no liner. (There is a higher-cost version available with a foam-lined wood case.)
Country of Origin:
- The Starrett 98-12 is made in the USA, clearly shared by Starrett on the their website and on the level's box.
- The Moore & Wright MWELM is now made in China.
Day to day use:
- The 2 holes in the center of the Starrett make handling and maneuvering easier and more comfortable than the single hole on the end of the M&W. Yes, the M&W can be picked up from the center using the lip, but it's not as as easy or secure as slipping fingers into holes (I know, that sounds funny).
- The clear liquid and red markings on the Starrett are easier for me to see than the green liquid and black markings on the M&W.
- On the Starrett, the short vial horizontally perpendicular to the main is on one end of the level, easy to see when leveling 2 planes of flat surfaces. On the M&W, the short horizontally perpendicular vial is next to the main vial and partially hidden by the frame.
Quality:
- The Starrett has a beautiful wrinkle black finish with impeccable metal surfaces and machining.
- The M&W is finished in what looks like black paint, over a casting with inconsistent texture and visible imperfections in the base metal including where it is machined. Functional but unrefined.
- On the Starrett, the cylindrical protection cover for the primary vial is metal. From what I've read, I believe it's brass with a silver-colored coating.
- On the M&W, the cylindrical cover is black plastic.
Summary:
When I bought these 2 levels, I got great deals on both. The Moore & Wright MWELM cost me $117 after tax, brand new. The Starrett 98-12 (TCAL version) cost me $181 after tax, used like-new from Amazon Warehouse. With the M&W being $64 cheaper and including the nice case, I really wanted to like it better.
Either of these levels will do the job.
But in the end, I found the Starrett to be a more user-friendly design, with better build quality, better material quality, better maneuverability, and better visibility. And, as a bonus, its overall finish is gorgeous.
So I kept the Starrett, and have used in now for just over 2 years, mostly for pool table leveling, for which the 12" level works great, but also to occasionally level machine surfaces.
