Yes, IMO Scalibor are excellent if you're going to use a drug-based preventative. They last 6 months, so you should need only one for the whole tick season. They also cover fleas, mosquitoes and sand flies, so if you're travelling abroad they are a great choice of preventative for several vectors of disease. They are the collar of choice in most European countries where dogs need preventatives more.
HOWEVER, I do know of one dog which had quite a bad reaction to a Scalibor collar. HE acted agitated, ran about the house, couldn't settle and seemed very strange in the hours after it was put on. These symptoms stopped when it was removed. So, some dogs do seem to react - but this is true of any drug-based preventative - they ALL cause reactions for some dogs.
The advantage of using a collar is you can remove it, if that happens. (Unlike a spot on or Bravecto.)
The downside of using a collar (or spot on) is that it will affect aquatic life if/when the dog swims, getting into waterways, and it will also expose humans in the house to pesticides. (Unlike Bravecto, which won't do either of these things.)
There's no perfect preventative, but for me it comes down to a Scalibor collar or Bravecto when I have to use one.

I don't have experience with the products you mention other than Seresto collars, which after only a few days, I had to take off my Basset as his skin under his chin started to react badly to this. We have used Beaphur collars in the past, with success however. I only use them if we start getting a flea/tick problem however. And for fleas when we had them in recent years, we used Capstar which got rid of them immediately, and vacuumed, sprayed everywhere. Problem gone. But we did buy some new Beaphur collars.

Nothing is perfect with regard to ticks but I have used Scalibor collars for several years and they seem to work quite efficiently. I have just bought some from petdrugsonline and a prescription isn't needed for these. I agree, the tick numbers are appalling this year. I took 12 off 2 dogs last Sunday whilst still in the car park!
