What size organization?
For enterprise
The leader is PaloAlto
Also Juniper
Cisco and checkpoint have decent market share....but their technology is old
Smaller business.....fortinet....maybe sonicwall or barracuda

So depending on your size....they address DDOS in different ways
Most always it includes a threshold limit...when X volume is triggered traffic is dropped
Also a proactive defense is a key point....what type of business are you protecting....then the advice can be more pointed...and less generic

We have about 300 users here and 30 servers, how about the parameters such as Concurrent connections and New connections per second?

We are thinking of Sophos and Fortinet

Yes. Here is one example from Corero

MTU Performance Max PDU 9100 Line rate, 10 Gbps 30 Mpps

Jumbo Frames Yes

Typical Latency <0.5uS

I would still say PALO for that size -- but its pricey
then again you get what you pay for and has many other features....
these days security is more about Malware - BOTNETS - Ransomware - malicious code and sites
my company rarely sees DDOS anymore
pretty much limited these days to a few industries...financial...education etc

these guys have decent GUI also - not Cisco tho

Fortinet would be my choice for the smaller and mid size company if budget conscious

here is a report that has them at the top

and a gartner link - from fortinet

PAN was best but costly and Fortinet was more affordable

Can also check out forrester report (though old but relevant) on the various key DDoS providers, mainly on cloud service and on premise. Enterprise support can still consider DDoS cloud service like in your case if server publicly accessible - more worthy as the attack scale up beyond a on premise for those system.

Regardless, of interest below is info on Fortinet :

Fortinet partners with Verisign for a cloud-based DDoS offering for those customers requiring a hybrid solution.  Customer references gave Fortinet positive feedback for detecting and mitigating layer 3 and layer 4 attacks, as well as for its on-premises implementation services and ongoing technical support.

 One shortcoming of the standalone Fortinet DDoS solution is that it cannot inspect SSL traffic. Customers rated the firm below-average for reporting and visibility in areas ranging from the ability to customize dashboards and reports to executive level and compliance reporting.  

Existing enterprise and service provider clients of Fortinet that need an on-premises DDoS solution as part of their hybrid strategy should consider Fortinet.
