Nigel - that website is wrong.
At higher temperature and ph the toxicity increases. That website has it backwards. With that in mind, we can't take anything stated there seriously.

As for which one is best, whichever one will be done properly. Taking me for example, I'm a ridiculously busy college student that doesn't have time for daily water changes. Fish in cycling is a bad idea for me.
For someone that's impatient and has the time then a fish in cycle is a great idea.
+1 that website is wrong
Mebbid, I understand where you are coming from but for me I choose to fish in cycle because I believe it makes for a much more stable and efficient cycle.
OP. If you stock and feed the tank sensibly there is absolutely no reason any fish will come to harm during a fish in cycle. The bacteria will grow steadily and proportionally to the nitrogen that is made available without erratic spikes during each phase of the cycle.
You do not have to change water everyday IF you start the cycle with a sensible bio-load for the size of tank you are cycling. All you have to do is monitor the levels everyday. In my experience I didn't see ammonia record anything above 0.25ppm throughout the whole cycle and didn't even catch the nitrite phase.
In theory a fish in cycle will take as long as it takes to add your last fish but the beauty is that you can stock the tank slowly and not really have to worry about when the cycle finishes just monitor the parameters. You can if you want change water at your leisure, you don't have to worry about removing food for the bacteria because the cycle is moving along steadily and WILL inevitably cycle. It is so easy to do if it is done properly.
Even more reason to go fish in if you are using seeded media.
A seachem ammonia alert is also a good investment if you go fish in. Mine never once left the safe zone.
Good luck
