As my question before was a bit weird (no definite answer could be given), I try it to formulate my question differently:

When comparing these two options:

30-40 Mbit/s download speed (LTE), but with a wireless router. 
(speedtest said 31 Mbit/s)

20 Mbit/s download speed (DSL), with a wired router (4 GigEthernet Ports)
(ISP says 20Mbit/s)

What shoud be considered when comparing these options? Is the first option (LTE with a wireless router) still better because of those 30-40Mbit/s download?

Credentials are speed and availability for 4-6 users.

I really just want to know how big of an impact the fact is, the LTE/WLAN is a shared medium and half duplex, so if those 30-40Mb/s (LTE, wireless) just seem to be better than those 20Mbit/s (DSL, wired).

EDIT: I want to know if the bandwidth difference between my two options above (which is around 10Mbit/s) is compensated by the fact, that the wireless router in my first option is half duplex and a shared medium and the router in my second option is not.

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise.

If i had to make this choice, this is how i would weigh up my options. The end choice will be your own.

Some things to consider:

  • Am I planning on making a service on my network available to the internet?
  • Do I need to use VOIP or real-time applications on this connection?
  • Am I going to be using this connection for gaming?
  • Do I only need this connection from the home? or will i be on the road?
  • Does the LTE connection have a monthly CAP or usage window?

Average Latency:

  • LTE (seems to be averaging here in the US about 90 ~ 100ms)
  • DSL (googling averages i found 44ms ~ 65ms)

Radio back-hauls can have a lot of varying latency. (jitter) Depending on what you are trying to do with the connection, it can be devastating to the user experience.(VOIP,Skype,Gaming)


Type of NAT:

  • LTE = Carrier Grade NAT (AFAIK you do not get a publicly accessible IP.)
  • DSL = Global IP Address (it is uncommon to not have a public IP.)

If you do not plan on port-forwarding anything, using P2P, or gaming. this aspect wont matter much to you. (If it does matter to you, ask your provider if its possible to get a global IP address.)


Gaming:

  • LTE (depending on how the game connects, server/client vs P2P) it may not even be possible behind this type of NAT
  • DSL Although it doesn't have the best latency compared to other network types.
    It does work out alright for those unfortunate enough to not have a choice.

VOIP

  • LTE probably not going to have a fun time trying to get this working correctly, the provider sells lines on the same tower. :)
  • DSL it is doable with the proper QOS rules and jitter buffers

Full-duplex or not?

  • LTE = Half-duplex, unless its LTE-A.
  • DSL = Depends on the actual type of DSL offered, DSL vs ADSL & VDSL. (Most DSL subscriptions these days are full-duplex AFAIK)

    Oh !! I wondered over what you said about the type of NAT used when accessing the internet via LTE, as I thought my router does "normal" NAT (which is connected to the ISP via LTE) But know everything makes sense! Because yesterday I went to "whatsmyip.com" and it showed to me that I am (according to my IP) located in the capital city of my country (which am really not). But with Carrier Grade NAT, this makes sense indeed! Thanks! – watchme Jun 16 '18 at 17:25
