IMO Felco secateurs are the only way to go for your personal use. Felco 2.
Felco 2 = 200t for hand pruning!
I've been in the horticulture biz, 26yrs all up and only ever had 3 pairs, the first ones I lost after about 10 years, I have one pair here in Bermuda and one in Tassie.
The balance is perfect, they sharpen well, the blade is replacable, nothing breaks. The only down is the red plastic on the handles on my pair here has come off, but it would be no problem to get some shrink tube and replace it.
I too have the pouch on my saw scabbard (the Weaver leather one) great for climbing a prune job.
If you were getting secateurs for others, I wouldn't hesitate with the Corona ones. I bought a dozen for apperentices and they are just fine. If they continued in the biz, then an investment in Felco's is their choice. They are not cheap, but then neither is a 200t!
