I think you'll be happy. I've been playing with them lately to see if I want a pair. They strike me as excellent if you don't have unrealistic expectations. FOV is good but not excellent (ala the Conquest). Control of CA is very good on axis but suffers a bit off axis, I can't remember how the Conquest was in comparison, it's been too long but I recall it being similar. The Monarch is certainly worse in this regard in my experience. Sharpness, color, contrast, stray light control are excellent. The focuser on the sample I've been playing with is excellent. The size and weight are excellent. They're not alphas, they're still a clear step behind the SF. But they are a very clear step up, for me, from the Conquest in terms of focuser, contrast, color, stray light control / viewing under challenging conditions, and just all around how enjoyable they are to use and how good they are as a birding tool. They are a clear step up for me, as well, from the MHG, basically the same binocular but better in near every way (perhaps a bit less flat of a field / more noticeably rolls off at the edges but doesn't bother). If you don't need the light weight and compact form, a used EL will be a better binocular at the same price (though not better in every way, particularly not stray light). However, if you want that compact format and light weight, I don't know if you actually can do better than the SFL.
To be clear, my perspective is not based upon critical evaluations of star tests or some composition of numbers assigned to various measurements, but rather using the bins to actually bird, particularly in poor light / challenging conditions. Lately that means trying to get detail on fall migrants in the canopy or flying over against harsh blown out grey skies. It really performs there, as well as the EL at least, even if the edges are softer and it will lose out in a technical / allbinos type showdown.
