I mean most of us here have yet to play a real game with the new tome (I dont really give much for Tabletop Simulator)
Why? Because it is digital? And digital books are not real books? I can get this point in case of 40k, which has way more problems, but either system is very good and close representation of real tabletop experience. I see no reason not to consider TTS game results (other than insane amount of some unit types which are not as easy to access IRL, but it is also a matter of time for dedicated competitive players).
since they can summon bodies onto an objective etc.
And what bodies would it be if not skinks again? Maybe saurus, which I mentioned. What is the point of summoning a carnosaur turn 4 and have about 40% chance to even get it into battle? I'd better summon a couple of sallies and 100% fry what I want with ranged attacks. Same with all other options. You have to wait at least 1 more turn to rely on them doing anything after summoning them. This means, that the most appealing units are those that do their job from the moment you have summoned them. Which, once again, leaves us with skinks, salamanders, saurus and guard.
but that might be why we see the current summoning so different
I don't really see how it is different. Exactly the same mechanics with more limitations. I don't think, that we suffer from it, but it doesn't make it good. Everything more expansive than 10 CCP is just not worth summoning, maybe, except kroxigors. Heroes which use their abilities in combat phase maybe ok if you happened to lose them early on, maybe ok, but that's it. I am not disappointed that we cannot summon wave after wave of skinks like before. I am disappoineted that there are 3-4 obvious choices and 3/4 of the summoning lists is plain useless.
Edit: Will the most often answer be to summon 10 Skinks? Likely. But there will be situations where you want that one Salamander, or another 3 fresh Terradons to bomb something, or call in a Terradon/Ripper Chief because you didnt need them until turn 3 etc., or a new Skink hero.
I already mentioned salamanders. For 10 CCP they are the best thing to summon in terms of damage and can be called early on. Yes, summoning chief may be useful, but what if: 1) I won't generate enough CCP because of bad dice before turn when I need him? 2) Will my slann/astrolith be in a good position to summon it? 3) Shall I have free LoSaT to teleport it in such a position if not? 4) Will it make them more vulnerable if I teleport them in such position? Maybe they won't be where they need to be if I do that?
After such considerations I'd rather take chief with me in the first place and won't be concerned about such things. And this doesn't suddenly make our summoning a toolbox, because we are still stuck in 10 CCP part, except, maybe, kroxigors. Previous summoning were way closer to toolbox IMO, because we could indeed summon the stuff we needed. If the list were about bodies, we could summon big monster later. If we brought mostly monsters, we could summon chaff, etc. etc.
