Interested in moca - got a few questions (alien.top)

I've got a new build in the UK. Rather annoyingly there is standard UK Aerial cable to various places in the house but not ethernet. This is stapled to the stud work so I can't use it to pull ethernet through.

Enter moca (I think)...

Each of the terminals has a separate line that all converge under the stairs (imagine a star-network topology).

Got a couple of questions:

I have a particular device that does not use much network < 1MB per day and doesn't require "high speed". Given this is an entirely separate line, am I ok use a cheaper, passive, 10/100 Moca 1 device here or are these fraught with problems?
For the other devices, I want as high speed/low ping as possible so will be using Moca 2.5. My question is, compared to ethernet, what am I not getting/what will be worse? (I was unable to get this answer from Google strangely - it just says its nearly-comparable to ethernet, but doesn't tell me what nearly means)

I missed answering question #2. So the Ring Topology happens when you have 1 MoCA adapter connected to the switch, then to a splitter, then all coax connected to that splitter, then to the corresponding MoCA adapter (nodes). This saves you money as you will need less MoCA adapters (i.e., for 2 nodes, you only need 3; for 3 nodes, you only need 4).

What you are planning to do is to use it as an ethernet alternative, which will be a 1:1 ethernet replacement. That will be expensive indeed, but will give you dedicated lines per node/device. If both MoCA adapters in the line are MoCA 2.5, then you have the full 2.5 gbps bandwidth at your disposal, if the device has a 2.5 NIC and your switch has 2.5 ports.

Ah ok - I wasn't planning on using a splitter, I would just going to stick a device on each end.

So given this, it does make sense to go for the cheaper option as listed in [1] for one of the devices that doesn't need the bandwidth - right?

15ms ping is quite high isn't it? Unless what you are quoting is to an external server over internet.

Yup, up to you. 15ms is external.
