Moose sum up very well on the pros and cons on camera and film scanner.
I believe the Nikon flare problem is mainly due to its lens system. I
once sent my 4000ED to Nikon for cleaning, they insisted they had
cleaned the interior but I found there was zero improvement.
Shallow DOF is a problem for the Nikon on mounted slides but film strip
is okay.
Nikon scanner not only emphasizes scratches, it also emphasizes grain.
After my Nikon's dead I had scanned more with Epson 4870 and V800. I
found I like the results more despite they give softer look (need more
sharpening). The major problem with the Epson is D-Max, it don't do well
on slides but negatives are okay, fortunately most of the shots I made
were on negatives.

I tried and rejected this solution years ago. Using a 5D, 80/4 auto,
bellows and slide copier, my results were pretty good, as good as my
Canon FS4000US film scanner with old film, lenses. I imagine it would be
fully as good now, maybe even better, with 80/4 auto and A7 or E-M5 II
in HR mode and 60/2.8 Macro lens.
But it's not about that, it's about madness and work flow. Madness is
spotting images that wouldn't need it if scanned on a scanner with IR
channel and proper software. Work flow is changing the frame and making
a manual exposure for every "scan". My little scanner will automagically
scan a 'stick' of six exposures or four mounted slides unattended. My
flatbed will do up to 30 with six frame 'sticks' or a dozen slides at
once, but at a bit lower quality, still with IR channel.
Silver based B&W film is still a problem, as IR cleaning doesn't work.
Fortunately, I personally have little of that. Kodachrome was a problem,
but at least VueScan and Silverfast have made software improvements that
do a god job of cleaning up KR.
CH found the camera approach fine for digitizing his collection of
slides. With flash from below and a stage with stops to position the
slides without fuss, he could go through a lot of slides quickly. The
scanner is much slower, but runs unattended.
The killer for me was spotting. I simply will not do it on film that can
be scanned and cleaned automatically. I suppose there may be people for
whom it can be a form of meditation. I spend at least enough time post
processing images as it is.
Now imagine Tina, who has scanned many thousands of images, and has who
knows how many still to do. Unlike me, and I imagine, you, she posts
many/most of them for stock sales. She doesn't just focus on the few
best shots. With Nikon scanner with automatic slide feeder and film
strip feeders, thousands of frames can be scanned while leading a life.
CH used the camera approach in part because of the flare problem with
his Nikon scanners. If that's what Tina has run into recently, her
sample shows it's gotten very bad on her scanner. The only solution is
an expensive and/or difficult cleaning of the internal mirror (or a
back-up). The other problems with Nikon scanners are relatively shallow
DoF and a fairly coherent light source that emphasizes scratches, etc. I
chose a Canon scanner for the more forgiving light source and greater DoF.
