I've tried several Tena, and they've been changing names and products around pretty regularly so it gets confusing to try to keep track of, but the last batch I bought were Tena Slip Maxi (plastic version), and they're okay. (I'm wearing one right now in fact!) Tena make good-fitting, comfortable diapers and don't overcharge for them, my main complaint is they tend to use very short standing leak guards. Although I tend to see those as "leak stoppers for wetting", their intended purpose is, as they are commonly called in japan, "poop-stoppers". So maybe tena just didn't intend their product for fecal incontinence?
Today the diaper I'm wearing is called a "Tena Slip Active Fit", ABU sells them here:

This appears to be the name they've settled down on for their tena slip maxi of the plastic-shelled variety. They've got four two-use tapes, no tape panel, and a very soft smooth plastic shell. The leg elastic is
very strong so they "hug your butt" rather nicely, but they have
no front or rear waistband elastic. The tapes hold good to the front, but I've experienced problems with them pulling loose from the back on occasion. Padding is medium thickness and appears to have a lot of sap. They swell a lot when wet but I haven't seen them wick very well so they don't get much use out of the padding in the back, and with the short leak guards they will leak only after a few wettings so not usable for me overnight.
(last year I tried out some Tena Slip Basic to see if they were going to be my new daywear, they're a low/no sap, all white version of the TSM, but are significantly cheaper, if they still sell them)
