Sorry to hear Lyonar not working out for you. I hope you like the Alabaster Titan archetype that came with the Unearthed Prophecies expansion. It’s a little different and refreshing to finally have a new archetype for them.
Between the two decks, Golems are definitely stronger in this meta. Wall Faie decks are running around, surrounding Obelysks to prevent spawns, as well as the typical Chromatic Cold shutting them down (though the new card Reassemble helps).
Phantasm punishes Obelysks so heavily, and Plasma Storm does more to Obelysk decks than Golems. Dispel is just more common nowadays too. EMP in particular has seen a lot more play, so it would shut down every Obelysk played. Even Vetruvian, thanks to Superior Mirage, punishes Obelysk decks if you use Dunecaster on a wind dervish.
Obelysk decks are still strong, but there’s a lot working against them right now. I feel that Golems are a safer choice for today’s metagame. They’re not as fast as Obelysk decks, but they can play a long game if necessary.
In case you haven’t heard, Golem/Flying hybrid lists are now growing in popularity. Their draw is insane, and the flying combo (Azure Summoning + 3 Skywing + 3 Dragonlark and possibly 1 Nosh-Rak) fits cozily into the Golem shell. I would argue it to be the strongest Vetruvian archetype if not the strongest deck in the game right now.
I know, all this chatter to help you choose between 2 decks. But I would say Golems are stronger. Remember, rocks…rock! (cringes internally)
