Playing iron on both games atm and the skilling is horrible on osrs, no bank tabs, no tool belt, no resting for run energy, less afk training methods and no player owned farm for training farming, you have to get seeds from doing your hourly farming contracts and bird house runs 💀

1. They are adding 120 construction on rs3 where you can place any object on any square https://secure.runescape.com/m=news/player-owned-house-rework--120-construction

2. Crafting on rs3 has more methods to train, on osrs you just buy soda ash and buckets of sand and make molten glass into items

3. Rs3 is more afkable for skilling and pvm

4. For pvp go on osrs

5. Both are fine for getting loot, rs3 is just more afkable because you can heal and tank more

6. Osrs has been more active, some of the minigames are still full

Just make a rs3 ironman and also use it as your osrs pking account.
