Reading this comparison I do not really ee the XA2 as enhancement

Plus, the design of the XA2 is reminiscent of the Nokia N9 - flat top and bottom, rounded corners. At least to me.

Be careful when comparing the X & XA2 by core number. As you can see:
Xperia X:
Hexa-core (4x1.4 GHz Cortex-A53 & 2x1.8 GHz Cortex-A72)
Xperia XA2:
Octa-core 2.2 GHz Cortex-A53
While XA2 has 8 cores, it's 8 times the simpler less advanced A53 core, while X has a big-little cluster with four simpler A53 cores and two more advanced A72 cores. This could have some advantages in single core performance and also in the rather important "race to idle" (getting task done as soon as possible so that the phone can quickly return to low power states).
On the other hand, it might still not be really noticeable with real world usecases (maybe people already did some comparisons/benchmarks on Android ?).

XA2's Snapdragon 630 uses big.LITTLE as well. 4 x 2.2GHz + 4 x 1.8GHz with the 630 vs 6x 1.2GHz + 2x 1.8GHz with the 650. Watching AIDA on various benches on my Xperia X, I rarely ever get the more advanced cores to spin up, so I don't count on them doing a lot.
The lithography and clock speed differences are monumental. At worst, the 630 will be as fast as the 650, but with much less power consumption.
JP1 is a dual core 1.4GHz Krait 300, with really slow (by modern standards) LPDDR2. That's a huge bandwidth and clock/core hit. That's why it's slow.

Because it's not. It's a low-mid range phone, whereas X was almost top of the line.
Specs are almost the same. So I don't understand what clovis86 is so excited about.

My claim is that for most intents and purposes the XA2 isn't (much) faster than the JP1, despite the much newer tech.
From Wikipedia: Cortex A53 scores 2.24 DMIPS/MHz; Krait 300 scores 3.39 DMIPS/MHz. Converted to their maximum frequency on these devices: A53: 4928 DMIPS. Krait 300: 4746 DMIPS. Based on this, the A53 at 2.2GHz is barely 4% faster than a Krait 300 at 1.4GHz.
Sure there are other factors, and yeah the 630 has four times the cores, but I'll kinda doubt you'll notice that when doing some browsing.
Given my experience with a A53-powered device, I'm not too compelled to buy another one.

Already have an XA2 (waiting for SFOS 3), used xperia x before with sfos and andy. and user experience is totally different even specsheets say otherwise!

All that I can tell is that XA2 is also running really smoothly on Oreo.
I can compare to the X before I switched it to SFOS and we are talking about 2 different experiences.
