The lack of apps on WP is still hard to swallow. Even with the apps that are available, many of them do not match up with the quality and features of their Android and iOS counterparts. I'm still waiting for a proper implementation of Facebook Messenger that matches what Android/iOS offers. Some vital regional apps are still missing. No Pocket, no Flipboard, no Chrome/Opera/Firefox, no Temple Run, no "proper" XDA app that allows posting, no codecs for unsupported audio/video formats. The list goes on. On the other hand, I can't find a credible alternative to HERE Drive for Android, and Mehdoh is the best Twitter client I've ever used but is WP-only. But as a whole, the app situation for WP is still pretty bad compared to the competition.
If you don't care about apps, however, the OS itself is excellent. It beats iOS for offering a customizable start screen, and it really trounces Android at performance and stability, especially on low-end hardware. The problem is that you have a fast and reliable OS, but one that is annoyingly gimped functionality-wise. WP has the potential to become great, but at this point in time I definitely regret switching over to it.
I guess it would be if you're an app junkie but even if you aren't, the Windows Phone store could use some more variety. The quality of the apps I've used so far have been great. I'll like an app even more if it's UI is as close as possible to the native UI of the OS. Some apps have come "close enough" but I still enjoy using them (e.g. Kik). As for Facebook Messenger, it's integrated with the built-in messaging app. And it's easy to switch between SMS and Facebook chat (see here
). A separate app for Facebook chat isn't necessary.
I don't know about the apps you mentioned because I don't use them and I've never heard of them (except for the browsers). However, I do know that Nokia recently rebranded their exclusive WP8 apps and made them available to non-Nokia WP8 devices (see here
Also, WhatsApp for WP8 received a major update as well as new features. I hope Kik gets a similar update too.
