I've never used the previous gen Met but the current one is a an absolute gem of a reel for me and I absolutely love it.
I also have a Curado 150mgl and it is great for what it is, like really great. It surpasses the Met in some areas.
For one I find the breaking system in the C. more reliable and better developed, I think this is in part because of the 6 pins, but perhaps more so they have tuned the way the dial works. I feel on the Met even very small incremental movements on the dial have a massive effect on the breaking profile which leads to a very narrow range of useable adjustment. The Curado, on the other hand, allows for much more fine tuning and, overall, the breaking experience leads to some pretty long casting and a lot of fun when you want to dial it in for a "free spool" type of feel when chasing that last few percent of casting distance.
I'm not often chasing that anymore, mind you, and so I find myself more than comfortable just setting and forgetting either reel and using it, within it's normal fishing parameters, to great effect and with long casts. non-magnetic breaks feel much more natural to me and I appreciate that I cannot feel the magnets pulling on the spool.
Back to the current gen Met, it is a far better reel than the Curado in every other way. It is more solid feeling, rock solid gearing, smooth, and has a wonderful "resistance" that makes every turn feel identical, whether you are hopping a jig or winding a spinnerbait with alot of drag in the water. The Curado, by contrast, feels less natural doing just about everything. It doesn't feel like the reel is helping pull that big spinner or winding that big fish or what have you. It just doesn't feel "strong"?
I'd choose the Curado 150 for jerkbait fishing every time. There is a feeling to this reel, that I get from alot of well made, more cost effective reels, that isn't quite a feeling of "smoothness" but a feeling of "nothingness". I like this feeling of "nothingness" very much when picking up slack with a jerkbait. I'm also getting better casting distance and a more reliable breaking profile as I desribed above. But for everything and anything else I'm choosing the current gen Met.
I'm sorry this doesn't directly address your question, but I hope it helps none the less.
