Replacement for Cisco 24 port 3750Gs?

Hi,

On the back of this post:https://www.reddit.com/r/networking/comments/hdtasy/48_port_access_switches/

We have four x 3750G 24 port switches for the core switch/distribution switches. What would you recommend as a vendor, given the below details? Again, there'll be budget constraints and Cisco is known to be very expensive. I'll probably end up using either fs or Aruba switches for the access layer dependent on price.

Looking here:https://blogs.arubanetworks.com/spectrum/aruba-recognized-by-gartner-as-a-leader-in-2019-magic-quadrant-for-the-wired-and-wireless-access-infrastructure/

It certainly appears that Aruba is "up there" with Cisco but I can't find anything for 2020 and that may even include Aruba's excellent WiFi which helps edge them that far, but I'm not so sure if they'd be a good fit? Would Aruba 2930s be any good? Or any other model? Or even Cisco if there's not a huge price difference. Coming from a Cisco background, I'd want a Cisco like CLI. That's the case on Dell switches and apparently also on the fs switches too. We will probably move to Aruba WiFi too in the end.

I've noticed that Aruba have the ARUBA 3810M 24G 1-SLOT SWITCH (JL071A) model. I can't imagine why we'd need anything higher when we're not a data centre, and this wouldn't be used in our data centre either tbh (for backup) In the DC, we also have another 3750G switch which would be replaced, but I believe it's just there for DR purposes so nothing beefy is needed even though it's in the DC.

We have around 80 members of staff. Our requirements are fairly simple. The distribution switches merely have port-channel aggregations to our access switches. SVIs are here, and OSPF is here too.

Tbh only 14 actual ports are being used here, not 24 but I figured that's probably cheaper than their 16 port modular model? ( ARUBA 3810M 16SFP+ 2-SLOT SWITCH (JL075A) )For the core, right now it's a mess as the firewall goes back into the core, to go out to the internet but the switches also route to the firewalls, however, the aim is to essentially have the core connected to the firewall and push most of the network into there regarding routing. Then the switches swill switch as per the traditional layer three models.

Regarding switching capacity, there are around 80 users in the office and we're currently using gigabit links with I believe 10Gb/s fibre uplinks too. There's no need for 10Gb/s on either of the core/distribution switches across all ports unless of course there's a very little price difference. I can't really see a need for Aruba 8320 switches despite it being marketed as a series for "Core switches"

We have OSPF configuration running there, and we're going to remove the ACLs and push it into the firewalls tbh. Besides, we'll probably move most of the routing into the firewalls too. We have no MPLS/VPN requirements either. I believe the Cisco C9500-24Q-A would also be a good fit? As well as possibly an FS S5900-24S4T2Q but I might want to steer away from them for core/distribution

Regarding support, very little technical support would be required other than timely firmware fixes so we're not vulnerable to CVE issues. There's also an argument to be had for using multi-vendor equipment too on that basis. There are extreme switches that I haven't considered too.

I should note, we resell HPE care packs so we could get that relatively cheap too.

Any help would be appreciated

Thanks
