I remember his 8x32 FL phase very well. He ridiculed me for saying I preferred my 7x42 EDG overall to 8x42 FL because I liked the view in the EDG better at night where its field flattener lenses provided pin point stars almost to the edge of the fov. He said birders didn't need field flattener lenses which were nothing more than "gimmicks just like circus mirrors". When Dennis proclaims his latest love the "best" binocular none of us regulars take heed at all, it's just the latest episode "Dennis being Dennis".
As far as the original question asked at the beginning of this thread I would say that most of the objective members on the forum would answer no. The truth is the best roofs in the world aren't better optically than the best porros; however, the alpha roofs are usually better in all the other factors that make a great birding bino.
The alpha roofs are waterproof and the effort needed to focus them varies little under cold weather conditions which are problematic for many porros. The alpha roofs also focus much closer than most porros and I must admit that even though I love my porros I often take a roof just for this reason--bugs, butterflies, and flowers make some interesting subjects when viewed up close at 6x-8x magnification.
The alpha roofs are usually a much better ergonomic fits for most users and the simple fact they offer twist up eyecups makes them much more versatile than the average porro. When traveling by myself I'm perfectly happy with one of my porros but when my wife is accompanying me I always opt for a roof. When one user wears glasses and the other doesn't twist up eyecups are a virtual necessity.
I know this thread has morphed into a "my bino is better than your bino" (or in this particular case "my roof is better than your roof because mine has field flattener lens elements") as Dennis's threads almost alway do but I would like to address the original question asked in the tittle of this thread. When it comes down to the optical performance of the best roofs versus the best porros I would have to answer that no the roofs aren't any better. As I mentioned above the alpha roofs offer many features that may make them a better overall choice but superior optics isn't one of them.
