While I do not own any Taurus Revolver's a few of my fellow Club Member's do and I have shot them on occasion. Yes, they worked, but honestly they are not a S&W Revolver IMHO. Taurus revolvers are all about saving money and not about getting a better quality revolver - just my opinion of course. I'd think you would be better off with a S&W or a Colt than buying the Taurus.
You asked about porting which I personally do not like. they do help perceived recoil however they are also now for making the revolver noisier - a 44 mag needs no additional help in that area. It's also another thing to clean and maintain and might cause a little velocity loss. For me it's mostly about the additional noise. I would not own a ported pistol, but I am only one man - plenty like them.
I own a number of S&W revolvers, in no particular order:
3” 686+
2 1/2” 686+
2 1/2” Model 66
3” Model 13
6” Model 66
6” Model 14
4” Model 15
6” Model 17
6” K-22 Outdoorsman
5” Victory Model
3” Model 60
3” Model 36
1 7/8” Model 36
4” Model 625
I also own a few Ruger revolvers;
2 3/4” Speed six (9mm)
2 3/4” Speed Six (.357)
2 3/4” Security Six
4” Police Service Six
6” Security Six
Plus a couple Blackhawks in .45 Colt, a couple more in .357 Mag and a couple Single Sixes.
I also own a Taurus 905 as well as a Taurus 942.
Here are my thoughts on Taurus:
1) Taurus QA is poor, but to be brutally honest right now QA at both S&W and Ruger is also hit and miss. Taurus however has good customer service and will fix the problem promptly. That has not been my experience with Ruger.
2) If you get a Taurus that shoots, it’s a good revolver.
Will it be S&W good? It depends on what you are looking for, but the Taurus revolvers perform well for the money, in an era and market where new S&W revolvers are badly over priced and Ruger revolvers are not much better.
That goes double for N frame sized revolvers.
3) I don’t own any Colt revolvers. I don’t like their cylinder release, I don’t like the probability that they won’t be around down the road, whenever the holding company that owns them decides to sell them to another holding company, and I don’t like the fact that they are priced way too high for what you get.
4) In short, Taurus revolvers offer great bang for the buck nad if it gets more people interested in revolvers it’s a plus.
