Gearing is the ratio of front/back. The higher the ratio, the harder/faster; the lower the ratio, the easier/slower. In climbing, you generally are concerned with lower.
On your Ridley, your low gear is 30/26; on your Bianchi, it’s 34/25. Whether these are low enough for you to comfortably climb depends on your abilities and the hills you are climbing.
