I got a refurbished Sony Xperia Z5 Compact to replace my Galaxy S4 Mini, which is getting a little long in the tooth (still working fine, and a recent battery replacement helped, but browsing on it, which I occasionally do, is somewhat troublesome). The Z5 Compact has Android 7.1.1, which is much newer than the 4.2.2 on the S4 Mini (which, as I just learned here, will no longer have Chrome support), and of course has better specs. On the other hand it's significantly (31g) heavier. Haven't switched to it yet. I'm waiting for a better case than the rubber one I got. Hopefully I'll enjoy it and won't break it too soon (I've read it's a little fragile, and I tend to drop my phone occasionally, which the S4 Mini has survived beautifully).
