I have done Striding Edge several times, and it depends -
If the weather is good, warm, sunny, clear, and you have plenty of time there should be no problems. Just take your time, go carefully, and understand that you will be in for a longer day than for those other hills you've done
The problems come if the weather is bad - rain, wind, snow & ice, mist, then you need to be extra careful
Or if you're with a group of faster people, and constantly rushing and scrabbling to keep up
Or if you feel you have to get down by, say 5 o'clock because that's what you've always done
Just take plenty of food & water, enjoy it, and in summer it won't get dark till well into the evening
Don't be a hero. If you find you're nervous be willing to come off the absolute crest of the ridge; there are lots of minor paths & ledges
It's worth brushing up on navigation to be sure of getting off the summit safely
We're not yet at midsummer, you could try some other ridges first. Besides those mentioned, try the east ridge of Bannerdale Crags; Wainwright Northern Fells, Bannerdale Crags 6
