Comparing ICQ vs Skype is like comparing apples to oranges. Because your business is unique and nobody except you can decide, which is better for your company. But we can add some fun to your research and suggest some new comparison parameters.

Let's start with videos. We think that Skype has better video than ICQ

Ok, now let's compare the UI. Looks like ICQ has more user-friendly interface than Skype because it's bigger. At least on our screenshots

To compare the popularity of the solutions we counted how many alternatives people search for each of them on the Internet. And it turns out that Skype is more popular than ICQ

Now let's look at the recent activities of our competitors:

- Skype introduced Professional accounts (in 2017)
- Skype radically redesigned mobile and desktop apps (in 2017)
- Skype adds real-time translation to all VoIP calls (in 2016)

- Skype discontinues its video messaging app Qik (in 2016)
- Skype integrated with Slack (in 2016)

Looks like Skype was recently more active than ICQ (at least in our news). We also found some news, in which ICQ and Skype meet head to head:

2017 - Skype radically redesigned mobile and desktop apps to keep up with ICQ

In June, Microsoft introduced a completely revamped version of its Skype app, designed with a heavier focus on media-sharing, and other social expression tools, like emoji, reactions, and even a Snapchat-like stories feature. Now that new experience is rolling out to desktop users. Group chats are multi-colored, emojis can be used to react to what others are saying while in video calls or in text conversations. But there are some additions that will be useful in the new Skype desktop, despite all this social app envy. For example, a new media gallery can be viewed on the right side of a group chat, which makes it easier to locate shared files, like documents, spreadsheets, photos or other media, that had been posted into the group. So Skype gets more youthful in comparison to ICQ

2016 - Skype gets Bots. ICQ keeps calm

In the new version of the Skype for Windows 10, Microsoft added several Skype bots, the automated chat assistants that it introduced earlier this year in a limited preview. The new bots include those that can help you make travel arrangements, locate event tickets, pull in information from other applications and services and even keep you entertained. For example, the Skyscanner Bot lets you search for individual or group flights, return pricing information and route options. Then, it will provide a link where users can go to complete the booking.

2009 - Skype is now the most popular IM client to keep up with ICQ

Recently all Skype news are about commercial wars and not about the new useful features. Nevertheless, its popularity grows day by day. According to  exo.performance.network, Skype is not only the most popular VoIP service, but also the most widely used IM client (at least on Windows PCs). After chipping away at Microsoft's lead for weeks, Skype finally surpassed the MSN Messenger. And while Microsoft Messenger is pre-installed on large number of PCs, Skype requires that the user make a conscious choice to seek out and install the program..

How this statistics data has been obtained? exo.performance.network provides free widgets with PC monitoring tools. And these widgets collect data from about 20 thousands computers all over the world. So, the statistics is close to reality. But the paradox is that Skype becomes more and more unsuitable for IM chatting. The  design of version 4 almost makes it impossible to open two chat windows at once. Besides, if you use Skype on several computers, the chat history will be separated between them. Skype developers are more focused on money-making communication tools - VoIP and Video.
