You've been through such a vast number of cards, it seems like you should be giving us advice. You specifically like the Ink for the 5x in your major spend area, plus you like the Capital One for its use in boutique hotels.

Perhaps you prefer one airline over another, based on your location or destinations.
Perhaps you value Club access or cash back.
Perhaps you like short, frequent trips or need to move a family of 4 on long hauls. All that would make a difference in advice. But, regardless, your monthly spend exceeds many people's yearly spend, so you should be racking up the points at a tremendous rate.
